Fix checkpatch.pl checks regarding error prone boolean comparisons.
Replace explicit comparisons to false with the logical NOT operator
to improve readability and match kernel coding style.
These instances were remaining after recent cleanups in this file.

Refactor the device tree parsing logic in axis_fifo_probe() to reduce
verbosity and simplify error handling.
Remove the verbose error logging and goto logic. Instead, check
of_property_read_u32() return values directly and propagate error codes
immediately. This aligns the driver with modern kernel standards by
removing unnecessary error messages during probe.

Update has_rx_fifo and has_tx_fifo types from int to u32 in struct
axis_fifo.
The of_property_read_u32() function expects a pointer to u32. Although
the current code works correctly with int, using u32 aligns the data
structure with the Device Tree API and prevents potential
type-mismatch issues.

premainder_ie is computed as pwps_ie + wps_ielen, where pwps_ie is
already validated non-NULL earlier in the function. Pointer arithmetic
on a non-NULL pointer can never yield NULL, making this check always
true and misleading. Replace with a simple check on remainder_ielen.

Several error paths in tegra_nvec_probe() return -ENODEV instead of
propagating the actual error code from the called function. This
prevents probe deferral from working correctly when a dependency
(clock, IRQ) is not yet available.
Fix this for platform_get_irq(), devm_clk_get(), and
devm_request_irq() by propagating their return values. Use
dev_err_probe() for the latter two to suppress log messages during
deferred probing.
The remaining -ENODEV returns for missing device tree node and
slave-addr property are left unchanged as those are permanent
configuration errors unrelated to probe deferral.

fsleep() is the preferred modern API for flexible sleeping as it
automatically selects the best sleep mechanism based on the duration.
Replace udelay() with fsleep() to improve power efficiency.
init_display() is a driver initialization callback which runs in
sleeping context, so fsleep() is safe to use here.

In cvm_oct_rx_initialize(), request_irq() is called with
&oct_rx_group[i].napi as the dev_id:
request_irq(oct_rx_group[i].irq, cvm_oct_do_interrupt, 0, "Ethernet",
&oct_rx_group[i].napi);
However, cvm_oct_rx_shutdown() passes cvm_oct_device (an array of
struct net_device pointers) as the dev_id to free_irq():
free_irq(oct_rx_group[i].irq, cvm_oct_device);
Since __free_irq() matches the action to remove by comparing
dev_id pointers, the mismatched cookie means the IRQ handler is
never found, triggering a WARN and leaving the IRQ line permanently
allocated. This prevents proper driver cleanup on module removal.
Fix the mismatch by passing &oct_rx_group[i].napi as the dev_id
to free_irq(), matching what was used during request_irq().

Change type of local variable wpa_ie_len from int to u8.
wpa_ie_len gets its value either from elems->wpa_ie_len or
elems->rsn_ie_len which are both u8, and thus there's no reason
to cast them to int.
This allows rewriting ternary min comparison using the min() function from
linux/minmax.h as now both sides are unsigned.
Rewrite as well wpa_ie_len + 2 to wpa_ie_len + 2u,
to keep the expression unsigned and avoid overflows.

When user write() only to part of the screen, the driver still updates the
entire screen. That wastes CPU cycles.
Optimize by updating only the changed lines.
Also remove a "special case" in fbtft_mkdirty() as its only user is removed
in this patch.
Tested with an Adafruit ILI9340 (drivers/staging/fbtft/fb_ili9340.c).
Improvement is measured by a pair of trace_printk() at the beginning of
fb_write() and at the end of fbtft_deferred_io().
Update type Before After
====================================
full screen 196ms 200ms
half screen 200ms 124ms
quarter screen 193ms 81ms
one pixel 199ms 43ms
It is interesting to note that if the deferred IO's delay time (40ms) is
subtracted, then the time amount scales linearly with the write size.

rtw_write8() calls
Previously, the function used 16 individual and repetitive rtw_write8()
calls (8 for each channel condition) to set the filter coefficients.
The new implementation uses a table pointer to select the appropriate
swingtable and iterates through the 8-byte coefficient array using a
single for loop. This achieves the same result without changing logic.

keep the cleanup consistent with the rest of the function.

The dim2 driver currently uses generic pr_* logging macros for
reporting hardware errors. Modern hardware drivers should use the
device-specific dev_* logging macros.
This provides better context in the system logs by identifying the
specific hardware instance associated with the error or warning,
which is especially helpful in systems with multiple controllers.

The dim2 driver is currently too talkative in the system logs.
Informational messages such as node addresses and state changes
are useful for developers but provide unnecessary noise for
regular users during normal operation.
Move these non-critical info messages to the debug level using
dev_dbg(). This ensures a quiet log by default while preserving
the information for debugging purposes.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.

than 'objs*'.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

The framebuffer registration message is informational only and not
useful during normal operation. Convert it to debug-level logging to
keep the driver quiet when working correctly.

When CONFIG_FB_DEVICE is disabled, struct fb_info does
not provide a valid dev pointer. Direct dereferences of
fb_info->dev therefore result in build failures.
Fix this by avoiding direct accesses to fb_info->dev and
switching the affected debug logging to framebuffer helpers
that do not rely on a device pointer.
This fixes the following build failure reported by the
kernel test robot.

fbtft provides sysfs interfaces for debugging and gamma configuration,
but these are not required for the core driver.
Drop the hard dependency on CONFIG_FB_DEVICE and make sysfs support
optional by using dev_of_fbinfo() at runtime. When FB_DEVICE is disabled,
sysfs operations are skipped while the code remains buildable and
type-checked.
