Remove obsolete commented-out code that references unsupported chip
variants (ODM_RTL8723A, ODM_RTL8188E). This code has been dead since
the driver was added to staging.
Also fix the resulting formatting by removing the unnecessary outer
parentheses and moving the inline comment to its own line.

Replace usage of the custom FIELD_OFFSET macro with the standard
offsetof() macro in ioctl_cfg80211.c. This improves code readability
and uses the kernel's standard mechanism.
Also include <linux/stddef.h> in basic_types.h to ensure offsetof()
is available for this and future conversions.

Check the return values of send_control() and send_line_coding() during
device initialization in gb_uart_probe(). If these operations fail, the
device will be left in an inconsistent state, so propagate the error to
properly fail the probe.
Both functions call gb_operation_sync() which can fail with errors such
as -ENOMEM, -ENODEV, or -ETIMEDOUT. Ignoring these errors means the TTY
device would be registered despite incomplete initialization.

fbtft_probe_common() allocates a memory chunk for "info" with
fbtft_framebuffer_alloc(). When "display->buswidth == 0" is true, the
function returns without releasing the "info", which will lead to a
memory leak.
Fix it by calling fbtft_framebuffer_release() when "display->buswidth
== 0" is true.

Move the gpib drivers out of staging and into the "real" part of the
kernel. This entails:
- Remove the gpib Kconfig menu and Makefile build rule from staging.
- Remove gpib/uapi from the header file search path in subdir-ccflags
of the gpib Makefile
- move the gpib/uapi files to include/uapi/linux
- Move the gpib tree out of staging to drivers.
- Remove the word "Linux" from the gpib Kconfig file.
- Add the gpib Kconfig menu and Makefile build rule to drivers

IIO: New device support, features and cleanup for 6.19
The usual bunch of new device support, but also quite a bit of cleanup
of the core and older drivers which is always good to see.
New device support
------------------
adi,ad4080
- Add support for AD4081, AD4083, AD4084, AD4086 and AD4087 ADCs with
slightly different features to existing supported parts (max CNV clock
count, resolution etc)
adi,adxl380
- Add support for ADXL318 and ADXL319 which have reduced functionality
compared to other supported parts, particularly around event detection.
aosong,adp810
- New driver for this differential pressure and temperature sensor.
aspeed,adc
- Add support for the AST2700 SoC ADCs which differ in small ways from
already supported parts.
bosch,sm330
- New driver for this IMU (accelerometer + gyroscop) with I2C and SPI bus
support.
invensense,icm45600
- New driver for this family of IMUs with sub drivers for accelerometer
and gyroscope elements. I2C, I3C and SPI busses all supported.
* Supports ICM45605, ICM45606, ICM45608, ICM45634, ICM45686, ICM45687,
ICM45688P, ICM45689.
* Support basic features and FIFO.
maxim,max14001
- New driver for the MAX14001 and MAX14002 ADCs.
renesas,rzt2h
- New driver supporting the RZ/T2H and RZ/N2H ADCs found in various SoCs.
renesas,rznl
- New driver supporting the RZ/NL ADC found in various SoCs.
Features
--------
adi,ad5446
- Add a DT binding doc for the 29 variants currently covered by the driver.
- Add adi,ad5542 which is compatiable with the adi,ad5542a which was
already supported.
bosch,bma220
- I2C support including an I2C bus watchdog.
- Power supply control
- Data ready trigger.
- Low pass filter control.
- Debugfs register access.
- Add Petre Rodan as a maintainer of this driver (thanks!)
bosch,bmi270
- Add support for motion events.
fsl,mpl3115
- Add a dataready trigger and related sampling frequency control.
- Add threshold events.
infineon,dps310
- Add a specific device tree binding.
maxim,max30100
- Allow control of LED pulse-width in dt-binding. Optimum value depends
on physical characteristics of the device which contains this sensor.
mediatek,mt2701
- Add dt compatible for the mt8189.
rockchip,saradc
- Add rk3506 compatible which is functionally the same as the already
supported rk3528 (which is therefore the fallback)
st,lsm6dsx
- Make sampling more flexible when both fifo and events are of interest
by decoupling the FIFO fill rate from actual sampling.
Cleanup and minor fixes
-----------------------
core
- Document and add might_sleep() to iio_push_to_buffers_with_ts_unaligned()
as it allocates a buffer, typically just on 1st call.
- Add documentation for iio_push_to_buffers_with_ts() which is being used
to replace iio_push_to_buffers_with_timestamp() in new code as it
validates the buffer size. Make the deprecation of the old function
clear.
- Document that the store_to() callback in struct iio_buffer_access_funcs
may be called from contexts that cannot sleep.
- Document that the cb() provided to a callback buffer may be called
from contexts that cannot sleep.
- Cleanup up industrialio-backend.c comments.
- Call mutex_destroy() in cleanup of buffers.
- Call device_initialize() later to avoid having to call device_put()
before configuration is otherwise complete.
- Use mutex_init_with_key() to replace opencoded version.
- Use dma_buf_unmap_attachment_unlocked() to replace opencoded version.
- Reorder Makefile for pressure sensors.
various
- Uses sysfs_emit() to replace sprintf() in read_label() and other
callbacks that typically are used to write data to sysfs buffers.
- Switch to REGCACHE_MAPLE in various drivers.
adi,docs
- Fix up formatting of cross references and other kernel-doc issues.
adi,ad4080
- Fix wrong masking of product IDs.
adi,ad5446
- Use DMA safe buffers as needed for SPI.
- Drop a duplicate device chip specific data structure where two parts
are functionally identical.
- Fail probe if reference is not available.
- Split up the massive array of chip type specific structures into
separate structures as this tends to be easier to read and maintain.
- Add explicit of_device_id entries for all supported parts.
- Split I2C and SPI parts away from core to avoid ifdef complexity.
- Switch to devm_mutex_init().
- Make use of guard() to simplify code.
- Applying IWYU principles and reorder headers.
- Various other minor cleanup.
adi,ad7124
- Add debugfs to support single cycle mode, typically only used for cases
such as validate performance of the ADC.
- Various other minor cleanup including removing some layers of indirection
that weren't necessary.
- Add extended attributes to the temperature channel which follows the same
signal path as other channels.
- Replace the setup register allocation strategy with a simpler more
predictable one (a fix for OOB from this code follows later in this pull
request).
adi,adxl345
- Ensure dt-binding allows for both interrupt wired at the same time.
arm,scmi
- Replace const_ilog2() with the resulting value which ends up simpler
to read.
bosch,bma220
- Add correct SPI mode specification to the device tree binding.
- Fix up interrupt type in dt binding example to match that the driver
expects.
- Relax hard constraint on matching chip ID with a message only so as to
enable fallback DT compatibles to work.
- Use local struct device *dev to replaces lots of indirect look ups.
- Improve includes on approximate IWYU basis.
- Explicit of_match_table.
- Reset some registers during probe.
- Move to regmap.
- Ensure a timestamp is available when filling the buffer by using a
locally acquired one rather than relying on trigger top half running.
- Add a utility function to search value pair tables for a match.
- Various other minor improvements.
- Move code to avoid a false dependency of the core code on the I2C module.
bosch,bma400
- Improve register and field naming + organization. Use with FIELD_GET()
and FIELD_PREP() to allow dropping of shift defines.
- Use macros to define event related fields.
- Switch to an address lookup based on an index variable to replace lots of
very similar register macros.
- Rename activity_event_en() to generic_event_en() to better reflect what
it does.
- Improve comments around interrupt register handling.
fsl,mpl3115
- Factor out code for triggered buffer data collection.
- Use more consistent register field naming style.
- Use get_unaligned_be24() to get the pressure.
invensense,mpu6050
- Drop false requirement in DT binding for the interrupt. The driver will
be able to do less if one is not provided, but some features are still
available.
invensense,icm45600_i3c
- Fix missing return on failure to match part.
linear,ltc2688
- Use devm_mutex_init() so mutex_destroy() is called in tear down path.
- Use guard() to simplify lock handling in error return paths.
qcom,vadc
- Fix up some kernel-doc related warnings.
rohm,bd79112 and bd79124

ti,am335x
- Add range checks to avoid a compiler warning.
ti,pac1934
- Switch to system_percpu_wq.

placement with -ffunction-sections
When compiled with -ffunction-sections (e.g., for LTO, livepatch, dead
code elimination, AutoFDO, or Propeller), the startup() function gets
compiled into the .text.startup section (or in some cases
.text.startup.constprop.0 or .text.startup.isra.0).
However, the .text.startup and .text.startup.* sections are also used by
the compiler for __attribute__((constructor)) code.
This naming conflict causes the vmlinux linker script to wrongly place
startup() function code in .init.text, which gets freed during boot.
Some builds have a mix of objects, both with and without
-ffunctions-sections, so it's not possible for the linker script to
disambiguate with #ifdef CONFIG_FUNCTION_SECTIONS or similar. This
means that "startup" unfortunately needs to be prohibited as a function
name.
Rename startup() to gc2235_startup().

-ffunction-sections
When compiling the kernel with -ffunction-sections (e.g., for LTO,
livepatch, dead code elimination, AutoFDO, or Propeller), the startup()
function gets compiled into the .text.startup section. In some cases it
can even be cloned into .text.startup.constprop.0 or
.text.startup.isra.0.
However, the .text.startup and .text.startup.* section names are already
reserved for use by the compiler for __attribute__((constructor)) code.
This naming conflict causes the vmlinux linker script to wrongly place

Fix that by renaming startup() to ov2722_startup().

Destage the VCHIQ interface driver to drivers/platform/raspberrypi.
There is still the remaining TODO item of improving the documentation,
which can be handled post destaging.
Secondly, multimedia drivers like codec and ISP that rely on this
interface need to be upstreamed. And lastly, the drivers that facilitate
the shared memory between VideoCore and Linux, like the vc-sm-cma driver
and vc_mem char driver also need to be upstreamed.

Raspberry Pi downstream drivers using VCHIQ have changed a lot since
kernel version 4.4 mentioned in the TODO, and are tangential to the
destaing process - so drop those items from the list.
Secondly, the code indentation for the vchiq interface driver is not so
bad anymore since Umang's series (linked below) got merged, so drop it
from the TODO.

Move the VCHIQ headers from drivers/staging/vc04_services/include to
include/linux/raspberrypi
This is done so that they can be shared between the VCHIQ interface
(which is going to be de-staged in a subsequent commit from staging) and
the VCHIQ drivers left in the staging/vc04_services (namely
bcm2835-audio, bcm2835-camera).
The include/linux/raspberrypi/ provides a central location to serve both of
these areas.

The bcm2835-camera driver is replaced by the V4L2 bcm2835-unicam driver
that is already upstream. So drop it from staging.
This also simplifies destaging of VCHIQ MMAL, by reducing the users of
the MMAL API (this driver is one of them).

Fixes the following checkpatch.pl warning:
"Use ether_addr_copy() instead of memcpy() for Ethernet addresses."

The MOST I2C driver has been completely broken for five years without
anyone noticing so remove the driver from staging.
Specifically, commit 723de0f9171e ("staging: most: remove device from
interface structure") started requiring drivers to set the interface
device pointer before registration, but the I2C driver was never updated
which results in a NULL pointer dereference if anyone ever tries to
probe it.

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
Until now, all products with an amplifier supported by the cs35l56 driver
have shipped with Microsoft Windows pre-installed. The factory calibration
of speaker protection has therefore been done using the Windows driver.
However, products that ship with a Linux-based distro must be able to
perform the factory calibration procedure from within the Linux-based
environment. This patch series adds that support.
NOTE: unfortunately this is yet another series that is mainly ASoC but
also needs some changes to the HDA driver, and they have build dependencies
on the ASoC code. I suggest taking this all through Mark's tree and we'll
avoid sending any other commits to the HDA driver until it has all landed
in Takashi's tree.

We have very similar name functions (A)(B). Both gets component from
snd_kcontrol, but (A) is used in callback functions which is registered
through snd_soc_add_component_controls(), (B) is used through
snd_soc_dapm_new_widgets().
(A) snd_soc_kcontrol_component()
(B) snd_soc_dapm_kcontrol_component()
(B) is using very picky way to get component but using it is necessary in
ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly
using it without wrapper is very common way on ALSA.
To reduce confusions of similar function, let's use common way on (A).

The v4l2_m2m_buf_copy_metadata() function takes a boolean
copy_frame_flags argument. When true, it causes the function to copy the
V4L2_BUF_FLAG_KEYFRAME, V4L2_BUF_FLAG_BFRAME and V4L2_BUF_FLAG_PFRAME
flags from the output buffer to the capture buffer.
There is no use cases in any upstream driver for copying the flags.
KEY/P/B frames are properties of the bitstream buffer in some formats.
Once decoded, this is no longer a property of the video frame and should
be discarded.
It was considered useful to know if an uncompressed frame was decoded
from a KEY/P/B compressed frame, and to preserve that information if
that same uncompressed frame was passed through another M2M device (e.g.
a scaler). However, the V4L2 documentation makes it clear that the flags
are meant for compressed frames only.
Drop the copy_frame_flags argument from v4l2_m2m_buf_copy_metadata().
The change to drivers was performed with the following Coccinelle
semantic patch:
@@
expression src;
expression dst;
expression flag;
@@
- v4l2_m2m_buf_copy_metadata(src, dst, flag);
+ v4l2_m2m_buf_copy_metadata(src, dst);
include/media/v4l2-mem2mem.h and drivers/media/v4l2-core/v4l2-mem2mem.c

reference count of the device by get_device() when matching but this
reference is not properly decreased. Add put_device() in
fmh_gpib_detach(), which ensures that the reference count of the
device is correctly managed.

This driver was not sending device clear or trigger events when the
board entered the DCAS or DTAS state respectively in device mode.
DCAS is the Device Clear Active State which is entered on receiving a
selective device clear message (SDC) or universal device clear message
(DCL) from the controller in charge.
DTAS is the Device Trigger Active State which is entered on receiving
a group execute trigger (GET) message from the controller.
In order for an application, implementing a particular device, to
detect when one of these states is entered the driver needs to send
the appropriate event.
Send the appropriate gpib_event when DCAS or DTAS is set in the
reported status word. This sets the DCAS or DTAS bits in the board's
status word which can be monitored by the application.
