right pointer.

With the recovery changes, if modem is brought down without FW
ready but WLAN driver is registered then shutdown call back is
called. This causes stability issue.
Make sure not call the shutdown call back if driver is not
registered. Also listening for PD notifications are enough even
for Subsystem restart so changing the quirks to take care of it.

Race condition observed during driver probe/remove and
suspend/resume because suspend/resume is not serialized
to work queue. Fix this problem by holding a wake lock
during wlan driver probe/remove to prevent system
suspend/resume.

Newer QCOM UFS host controller doesn't need to execute
the special LPM mode configuration when switching to SVS2
mode. This change looks at the host controller version
to bypass this special configuration for newer controller
version.

When event needs to be processed synchronously, event posting
thread waits for the completion. After completion, result from
the event work is retrieved and event buffer would be freed. But
if waiting thread gets interrupted then wait_for_completion API
returns failure and it also frees the buffer posted for
processing. Event work queue may accesses the freed buffer and
crash the system.
Fix the issue by properly synchronizing event buffer free between
caller and event work by checking for return value of
wait_for_completion.
