979ebc54cf ath11k: send beacon template after vdev_start/restart during csa
Firmware has added assert if beacon template is received after
vdev_down. Firmware expects beacon template after vdev_start
and before vdev_up. This change is needed to support MBSSID EMA
cases in firmware.

Hence, Change the sequence in ath11k as expected from firmware.
This new change is not causing any issues with older
firmware.

ef48667557 wcn36xx: Move hal_buf allocation to devm_kmalloc in probe
Right now wcn->hal_buf is allocated in wcn36xx_start(). This is a problem
since we should have setup all of the buffers we required by the time
ieee80211_register_hw() is called.

struct ieee80211_ops callbacks may run prior to mac_start() and therefore
wcn->hal_buf must be initialized.

This is easily remediated by moving the allocation to probe() taking the
opportunity to tidy up freeing memory by using devm_kmalloc().

1e2e8ee957 wcn36xx: Enable WOWLAN flags
Enable flags for

- Magic packet
- GTK rekey

Previous patches implemented the necessary code to switch these two on.
Standalone magic packet absent GTK rekey is pretty useless, so it makes
sense to flag both at once.

Once done it is possible for wcn36xx firmware to

1. Respond to ipv4 and ipv6 ARP/NS lookup requests
2. Bring the system out of suspend when a magic packet is received.
   Magic in our case is a simple ipv4 or ipv6 unicast.
3. GTK rekey whilst in suspend
   Once we wake from suspend the GTK will be updated as necessary

ebe7c1a663 wcn36xx: Add host resume request support
This commit is the corresponding resume() path request to the firmware when

bedf1169bc wcn36xx: Add GTK offload info to WoWLAN resume
Having enabled GTK rekey in suspend, we need to extract the replay counter
from the firmware on resume and perform a ieee80211_gtk_rekey_notify() so
that the STA remains verified from the perspective of the AP.

In order to enable the SMD command and response we need to pack the
existing command/response structures. Given these structures are currently
unused, there's no need to backport this as a fix.

CARL9170_LEDS selects MAC80211_LEDS even though its kconfig
dependencies are not met. This happens because 'select' does not follow
any Kconfig dependency chains.

Fix this by making CARL9170_LEDS depend on MAC80211_LEDS, where
the latter supplies any needed dependencies on LEDS_CLASS.

fb312ac5cc ath9k: Fix kernel NULL pointer dereference during ath_reset_internal()
I got this crash more times during debugging of PCIe controller and crash
happens somehow at the time when PCIe kernel code started link retraining (as
part of ASPM code) when at the same time PCIe link went down and ath9k probably
executed hw reset procedure.

Currently I'm not able to reproduce this issue as it looks like to be
some race condition between link training, ASPM, link down and reset
path. And as always, race conditions which depends on more input
parameters are hard to reproduce as it depends on precise timings.

But it is clear that pointers are zero in this case and should be
properly filled as same code pattern is used in ath9k_stop() function.
Anyway I was able to reproduce this crash by manually triggering ath
reset worker prior putting card up. I created simple patch to export
reset functionality via debugfs and use it to "simulate" of triggering
reset.    s proved that NULL-pointer dereference issue is there.

Function ath9k_hw_reset() is dereferencing chan structure pointer, so it
needs to be non-NULL pointer.

Function ath9k_stop() already contains code which sets ah->curchan to valid
non-NULL pointer prior calling ath9k_hw_reset() function.

Add same code pattern also into ath_reset_internal() function to prevent
kernel NULL pointer dereference in ath9k_hw_reset() function.

This change fixes kernel NULL pointer dereference in ath9k_hw_reset() which
is caused by calling ath9k_hw_reset() from ath_reset_internal() with NULL
chan structure.

568e7142a1 nfc: st95hf: remove unnecessary assignment and label
In function st95hf_in_send_cmd, the variable rc is assigned then goto
error label, which just returns rc, so we use return to replace it.
Since error label only used once in the function, so we remove error label.

205523bc06 ixgbe: reduce checker warnings
Fix the sparse warnings in the ixgbe crypto offload code. These
changes were made in the most conservative way (force cast)
in order to hopefully not break the code. I suspect that the
code might still be broken on big-endian architectures, but
no one is complaining, so I'm just leaving it functionally
the same.

b16dc6c2f1 ixgbe: use checker safe conversions
The ixgbe hardware needs some very specific programming for
certain registers, which led to some misguided usage of ntohs
instead of using be16_to_cpu(), as well as a home grown swap
followed by an ntohs. Sparse didn't like this at all, and this
fixes the C=2 build, with code that uses native kernel interface.

b6ce4a1c4b igbvf: convert to strongly typed descriptors
The igbvf driver for some reason never strongly typed it's descriptor
formats. Make this driver like the rest of the Intel drivers and use
__le* for our little endian descriptors.

de8447131d intel: call csum functions with well formatted arguments
The sparse build (C=2) found that there were two drivers
who had not been convered to call the csum_replace_by_diff() function
with sparse clean arguments.  Most if not all drivers force the cast
like this patch does. So these drivers are now joining the party
(a bit late), but with no functional change.

9fb8602e56 igb: override two checker warnings
The igb PTP code was using htons() on a constant to try to
byte swap the value before writing it to a register. This byte
swap has the consequence of triggering sparse conflicts between
the register write which expect cpu ordered input, and the code
which generated a big endian constant. Just override the cast
to make sure code doesn't change but silence the warning.

Can't do a __swab16 in this case because big endian systems
would then write the wrong value.
