GPIO core deals just fine with input-only controllers not implementing
the .set() callback. Remove the unneeded dummy implementation.

GPIO core already makes sure that offsets higher than the number of GPIOs
are never passed to controller callbacks. We can remove the unnecessary

Procedures for nvme-mpath IO accounting:
1) initialize nvme_request and clear flags;
2) set NVME_MPATH_IO_STATS and increase inflight counter when IO
started;
3) check NVME_MPATH_IO_STATS and decrease inflight counter when IO is
done;
However, for the case nvme_fail_nonready_command(), both step 1) and 2)
are skipped, and if old nvme_request set NVME_MPATH_IO_STATS and then
request is reused, step 3) will still be executed, causing inflight I/O
counter to be negative.
Fix the problem by clearing nvme_request in nvme_fail_nonready_command().

This was originally added by commit 8695f060a029 ("nvme: all namespaces
in a subsystem must adhere to a common atomic write size") to check
the all controllers in a subsystem report the same atomic write size,
but the check wasn't quite correct and caused problems for devices
with multiple namespaces that report different LBA sizes. Commit
f46d273449ba ("nvme: fix atomic write size validation") tried to fix
this, but then caused problems for namespace rediscovery after a
format with an LBA size change that changes the AWUPF value.
This drops the validation and essentially reverts those two commits while
keeping the cleanup that went in between the two. We'll need to figure
out how to properly check for the mouse trap that nvme left us, but for
now revert the check to keep devices working for users who couldn't care
less about the atomic write feature.

Running as nested root on MSHV imposes a different requirement
for the pci-hyperv controller.
In this setup, the interrupt will first come to the L1 (nested) hypervisor,
which will deliver it to the appropriate root CPU. Instead of issuing the
RETARGET hypercall, issue the MAP_DEVICE_INTERRUPT hypercall to L1 to
complete the setup.
Rename hv_arch_irq_unmask() to hv_irq_retarget_interrupt().

Some FW features may have variants on how to deal with in leaf functions,
e.g. H2C commands. However, from SW component point of view, it might not
matter which variant is supported exactly. In some cases, SW component may
just care whether any of the variants is supported or not.
So, introduce a concept of FW feature group which can manage a set of FW
features and can easily be checked if at least one of them is supported.
Since CRASH_TRIGGER will have variants and then matches the case mentioned
above, so redefine CRASH_TRIGGER as a FW feature group and add a variant
of type 0 for original handling.

For some implementation acting as GO under MCC(GO+STA), the GO's TBTT
might change after STA roams to another AP. This could result the new GO
beacon TX at the STA timeslot of GC+STA, causing GC beacon loss.
Therefore, if the GC detects beacon loss, it will pause MCC and remain
on the GO side for 100 TU to detect the new TBTT beacon.
Additionally, some implementation acting as GO under MCC might TX beacon
too close to the NoA period. The GC calculates timeslot pattern the TOB
(time offset behind) or TOA(time offset ahead) less than the minimum
RX beacon time, which leads to beacon loss. Therefore, disable the
beacon filter in this case. Then, if the GO's TBTT changed, the pattern
TOB/TOA greater than the minimum RX beacon time, the beacon filter should
be retriggered during MCC update.
Moreover, if the beacon filter is disabled initially but the GO timeslot
change, causing QoS null data detection fail, also pause MCC to detect new
TBTT beacon.

HW scan of WiFi 7 chips supports multiple op channel configurations.
When concurrency, fill two channels info to HW scan to avoid packet
lost.
However, the OP chan timing is arranged by FW, and the actual stay
period depends on AP. It's hard to calculate total scan time for once
NoA in advance. Therefore, change the scan back to GO OP channel every
200TU and TX beacon to ensure GC doesn't beacon loss. Additionally, add
a period NoA with large duration to ensure GC doesn't TX packet during
GO scanning and can still listen beacon at TBTT to update the new NoA
info after scan complete.

MCC require time to switch channel when changing timeslot. If GC TX
nulldata 0 while GO is switching channel, GO can't receive it. Therefore,
enlarge the GO NoA duration to cover the channel switching time.
However, the enlarged NoA duration might cause GC's timeslot less than
minimum of RX beacon time. Therefore, adjust strict and anchor pattern

When the bfad_im_probe() function fails during initialization, the memory
pointed to by bfad->im is freed without setting bfad->im to NULL.
Subsequently, during driver uninstallation, when the state machine enters
the bfad_sm_stopping state and calls the bfad_im_probe_undo() function,
it attempts to free the memory pointed to by bfad->im again, thereby
triggering a double-free vulnerability.
Set bfad->im to NULL if probing fails.

The dma_unmap_sg() functions should be called with the same nents as the
dma_map_sg(), not the value the map function returned.

Configurations with large numbers of FC rports per host instance are
taking a very long time to complete all devloss work. Increase potential
parallelism by using a per-rport devloss_work_q for dev_loss_work and
fast_io_fail_work.

On Google gs101, the number of UTP transfer request slots (nutrs) is 32,
and in this case the driver ends up programming the UTRL_NEXUS_TYPE
incorrectly as 0.
This is because the left hand side of the shift is 1, which is of type
int, i.e. 31 bits wide. Shifting by more than that width results in
undefined behaviour.
Fix this by switching to the BIT() macro, which applies correct type
casting as required. This ensures the correct value is written to
UTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shift
warning:
UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21
shift exponent 32 is too large for 32-bit type 'int'
For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPE
write.
