During recovery, there are cases where in WLAN driver running on
APPS can access CE register causing exceptions because of
hardware in reset state. Fix the issue by not resetting the
hardware in WLAN firmware during recovery but halt the CE and MAC
and reset the hardware only when reinitialization starts. For
this to work, wcn3990 ath10k driver needs to keep the clock and
regulator votes so that WLAN hardware will not go into weird
state because of not resetting it but cutting the resources.

During soundcard deregistration, free_chmap() is called as part of
pcm_free. This only frees downmix kcontrol as pcm has reference
only to downmix kcontrol followed by freeing of pcm pointer. The
other two kcontrol are freed as part of snd_ctl_remove(). However,
while freeing other two kcontrols, pcm_usr_ctl_private_free()
accesses pcm->streams which are already freed causing crash.
Fix is to add pan/scale & downmix controls as platform controls
instead of user control.

ION page pool and cma shrinkers return the total pooled
memory instead of the freed. This can result in an early
exit of ION page pool shrinker thus giving back less memory
to the system. For cma shrinker this change doesn't have an
effect since the callers of shrink_slab currently ignores
the return value.

Sde client customization is disabled by previous commit which
is propagated from other branch. After disabling this, 4K display
on HDMI can not be up. This is because when creating drm plane in kernel,
sde client customization will directly set possible_crtcs per plane
reporting to user space. When disabling it, user space's sdm strategy
could not get and assign correct pipes for 4K display.

This patch disables Rx and Tx engine properly while going to suspend or
shutdown. There are chances when BT SOC or client is going bad and
disrupts the UART SW state machine.
1.Do not allow double resource_vote and hence pipe connect at port open.
2.While going to suspend, close the HW resources forcibly to prevent
UART from going bad for the subsequent resume cycle.
3.Stop Rx engine gracefully even if clocks are off to obey the framework.
4.During resource unvote, if runtime PM is disabled then go for forced
suspend.
5.In case of fatal error, stop further IPC logging.
6.Add relevant log if the Rx pipe is not empty at the time disconnecting.
7.Prevent Rx byte entering in case of back to back loopback test, as
this causes data mismatch.
8.Add the logs correctly just after reading the status instead doing it
later which doesn't get logged in case of any failure.

Pagetable pgd is allocated in arm_smmu_init_domain_context and is freed in
arm_smmu_domain_free. Client can attach/detach domain without freeing the
same. This causes memory leak. This was introduced with

Free io pgtables in arm_smmu_destroy_domain_context, which is invoked at

In most code paths involving cgroup migration cgroup_threadgroup_rwsem
is taken. There are two exceptions:
- remove_tasks_in_empty_cpuset calls cgroup_transfer_tasks
- vhost_attach_cgroups_work calls cgroup_attach_task_all
With cgroup_threadgroup_rwsem held it is guaranteed that cgroup_post_fork
and copy_cgroup_ns will reference the same css_set from the process calling
fork.
Without such an interlock there process after fork could reference one
css_set from it's new cgroup namespace and another css_set from
task->cgroups, which semantically is nonsensical.

In order to simplify the implementation both in the driver

event and not using QCA_WLAN_VENDOR_ATTR_FTM_PEER_RES_AOA_MEAS.
This way we can also report the antenna array mask which was

Currently, ESR extraction control is configured from two paths.
First is invoked when Qnovo is enabled or disabled. Second is
invoked when the pulse train is done and ESR measurement is
requested. When the latter is run, there is a sleep time of 1.5
seconds that is essential for allowing FG to do ESR measurement.
However in that time window, if Qnovo is disabled for some reason
then ESR extraction control will be kept disabled unexpectedly.
Fix this by protecting both the paths using a mutex lock as well
as checking for qnovo enable status before disabling ESR
extraction control after measuring ESR.

Currently driver is enabling hsphy_irq and ssphy_irq at the end
of dwc3_msm_suspend() without any spinlock/mutex protection. But
if it happens that hsphy_irq or ssphy_irq gets fired right after
enablement of irqs, there is a chance that we might see warnings
related to unbalanced irq enable. This could happen due to flag
is not yet set to indicate phy irqs enabled in suspend(). This
might cause phy irq left enabled after resume and could cause
crash due to unclocked access in host mode. Fix the unbalance irq
enable by having mutex protection and also extend mutex protection
for dwc3_msm_suspend() and dwc3_msm_resume().
