The error exit path when rn is NULL ends up deferencing the null pointer rn
via the use of the macro CSIO_INC_STATS. Fix this by adding a new error

Some randconfig builds run into excessive stack usage with gcc-14 or
higher, which use __attribute__((cold)) where earlier versions did not do
that:
drivers/scsi/BusLogic.c: In function 'blogic_init':
drivers/scsi/BusLogic.c:2398:1: error: the frame size of 1680 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
The problem is that a lot of code gets inlined into blogic_init() here. Two
functions stick out, but they are a bit different:
- blogic_init_probeinfo_list() actually uses a few hundred bytes of kernel
stack, which is a problem in combination with other functions that also
do. Marking this one as noinline means that the stack slots get get
reused between function calls
- blogic_reportconfig() has a few large variables, but whenever it is not
inlined into its caller, the compiler is actually smart enough to reuse
stack slots for these automatically, so marking it as noinline saves
most of the stack space by itself.
The combination of both of these should avoid the problem entirely.

The added print statement from a recent fix causes the driver to fail

just add a dependency and remove the existing ifdef checks, rather than

====================
gve: Stats reporting fixes
This series addresses two issues related to statistics in the gve driver.
The first patch fixes a memory corruption issue that occurs when resizing
the stats region during queue count changes. By allocating the maximum
possible size upfront and aligning offset calculations with the NIC,
we ensure stability and accuracy across reconfigurations.
The second patch fixes the 'rx_dropped' counter by removing allocation
failures and incorporating XDP transmit and redirect errors to provide
a more accurate representation of dropped packets.

The gve driver's "rx_dropped" statistic, exposed via `ethtool -S`,
incorrectly includes `rx_buf_alloc_fail` counts. These failures
represent an inability to allocate receive buffers, not true packet
drops where a received packet is discarded. This misrepresentation can
lead to inaccurate diagnostics.
This patch rectifies the ethtool "rx_dropped" calculation. It removes
`rx_buf_alloc_fail` from the total and adds `xdp_tx_errors` and
`xdp_redirect_errors`, which represent legitimate packet drops within
the XDP path.

The driver and the NIC share a region in memory for stats reporting.
The NIC calculates its offset into this region based on the total size
of the stats region and the size of the NIC's stats.
When the number of queues is changed, the driver's stats region is
resized. If the queue count is increased, the NIC can write past
the end of the allocated stats region, causing memory corruption.
If the queue count is decreased, there is a gap between the driver
and NIC stats, leading to incorrect stats reporting.
This change fixes the issue by allocating stats region with maximum
size, and the offset calculation for NIC stats is changed to match
with the calculation of the NIC.

The ufs_mtk_clk_scale() trace event currently stores the address of the
name string directly via __field(const char *, name). This pointer may
become invalid after the module is unloaded, causing page faults when the
trace buffer is subsequently accessed.
This can occur because the MediaTek UFS driver can be configured as a
loadable module (tristate in Kconfig), meaning the name string passed to
the trace event may reside in module memory that becomes invalid after
module unload.
Fix this by using __string() and __assign_str() to copy the string contents
into the ring buffer instead of storing the pointer. This ensures the trace
data remains valid regardless of module state.
This change increases the memory usage for each ftrace entry by a few bytes
(clock names are typically 7-15 characters like "ufs_sel" or
"ufs_sel_max_src") compared to storing an 8-byte pointer.
Note that this change does not affect anything unless all of the following
conditions are met:
- CONFIG_SCSI_UFS_MEDIATEK is enabled
- ftrace tracing is enabled
- The ufs_mtk_clk_scale event is enabled in ftrace

The test case covers the scenario addressed by the previous fix;
reusing the existing udpgro_fwd.sh script to leverage part of the

a perfect fit.
Note that the mentioned script already contains several shellcheck

The udp GRO complete stage assumes that all the packets inserted the RX
have the `encapsulation` flag zeroed. Such assumption is not true, as a
few H/W NICs can set such flag when H/W offloading the checksum for
an UDP encapsulated traffic, the tun driver can inject GSO packets with
UDP encapsulation and the problematic layout can also be created via
a veth based setup.
Due to the above, in the problematic scenarios, udp4_gro_complete() uses
the wrong network offset (inner instead of outer) to compute the outer
UDP header pseudo checksum, leading to csum validation errors later on
in packet processing.
Address the issue always clearing the encapsulation flag at GRO completion
time. Such flag will be set again as needed for encapsulated packets by
udp_gro_complete().

pqi_report_phys_luns() fails to release the rpl_list buffer when
encountering an unsupported data format or when the allocation for
rpl_16byte_wwid_list fails. These early returns bypass the cleanup logic,
leading to memory leaks.

Yin Fengwei reported an RCU stall in ptype_seq_show() and provided
a patch.
Real issue is that ptype_seq_next() and ptype_seq_show() violate
RCU rules.
ptype_seq_show() runs under rcu_read_lock(), and reads pt->dev
to get device name without any barrier.
At the same time, concurrent writers can remove a packet_type structure
(which is correctly freed after an RCU grace period) and clear pt->dev
without an RCU grace period.
Define ptype_iter_state to carry a dev pointer along seq_net_private:
struct ptype_iter_state {
struct seq_net_private p;
struct net_device *dev; // added in this patch
};
We need to record the device pointer in ptype_get_idx() and
ptype_seq_next() so that ptype_seq_show() is safe against
concurrent pt->dev changes.
We also need to add full RCU protection in ptype_seq_next().
(Missing READ_ONCE() when reading list.next values)

Ensure that the exception event handling work is explicitly flushed during
suspend when the runtime power management level is set to UFS_PM_LVL_0.
When the RPM level is zero, the device power mode and link state both
remain active. Previously, the UFS core driver bypassed flushing exception
event handling jobs in this configuration. This created a race condition
where the driver could attempt to access the host controller to handle an
exception after the system had already entered a deep power-down state,
resulting in a system crash.
Explicitly flush this work and disable auto BKOPs before the suspend
callback proceeds. This guarantees that pending exception tasks complete
and prevents illegal hardware access during the power-down sequence.

There is no added value in efct_intr_msix() compared to
irq_default_primary_handler().
Using a threaded interrupt without a dedicated primary handler mandates the
IRQF_ONESHOT flag to mask the interrupt source while the threaded handler
is active. Otherwise the interrupt can fire again before the threaded
handler had a chance to run.
Use the default primary interrupt handler by specifying NULL and set
IRQF_ONESHOT so the interrupt source is masked until the secondary handler
is done.

The SCU MU driver has already supported the simple and efficient single-TX
and single-RX channel layout since 2021. The older multi-channel MU
configurations (tx0..tx3 and rx0..rx3) are less efficient in practice and
not needed.
Mark these legacy mbox-names and mboxes tuple layouts as deprecated in the
binding schema. The driver continues to support them for backward
compatibility in case firmware publishes the legacy properties.
The example section is updated accordingly to demonstrate the recommended
layout.

Not all IP implementations of EIP97 and EIP197 have the EIP and
MEM interrupts hooked up to the SoC, and those are not required
for functionality as status for both can be polled (and anyway
there's even no real need to poll, but that's another story).
As an example of this, the MediaTek MT7986A and MT7986B SoCs do
not have those two interrupts hooked up to their irq controlller.
For this reason, make the EIP and MEM interrupt optional on the
mediatek,mt7986-crypto.

The __free() annotation was incorrectly placed before the variable
name instead of after it, which resulted in the following checkpatch
errors:
ERROR: need consistent spacing around '*' (ctx:WxV)
+ struct device_node __free(device_node) *target = of_parse_phandle(np, "memory-region", idx);
^
WARNING: function definition argument 'idx' should also have an identifier name
+ struct device_node __free(device_node) *target = of_parse_phandle(np, "memory-region", idx);
As part of this cleanup, also remove the useless return statement
flagged by checkpatch.

The Realtek system controllers are already in use with only generic
'"syscon", "simple-mfd"' compatibles and are missing specific
compatibles as required. Add a schema with specific compatibles. The
labels used in .dts files serve as the basis for the names.
It's doubtful the child nodes upstream are complete and I don't have
documentation, so the specific child nodes aren't documented here. Of
the ones in use, bindings already exist for them.

Current binding document enforces presence of either port@0 (DSI in) or
port@1 (DPI IN/OUT), with port@2 (DP out) being optional. This bridge is
capable of DSI->DP, DPI->DP and DPI->DP, it is therefore perfectly valid
to have both port@0 and port@1 described in the DT, because this is fairy
standard DPI->DP configuration of this bridge. Replace oneOf with anyOf
to cover this configuration.
