Calling request_firmware() during suspend/resume operations is
buggy and error prone. Therefore a check exists in
request_firmware() to see if a suspend/resume operation is in
progress. In testing we've seen that a wakeup interrupt can come
in during suspend and trigger subsystem restart to call
pil_force_boot() before userspace has fully thawed. Since this is
not allowed the request_firmware() call from pil_force_boot()
fails with -EBUSY and the processor is never rebooted.
Register for PM notifiers to avoid calling request_firmware()
when suspend/resume is in progress. Within the notifier
synchronize any request firmware calls with suspend using a
rwsem. In the case where pil is called before suspend, the
suspend notifier should block on the down_write() during
PM_SUSPEND_PREPARE. When suspend is initiated before pil any pil
operations should block on the down_read() until suspend
finishes. Doing this should fix races between suspend/resume and
request_firmware() within PIL.

interruptible_wait_timeout returns a signed long, so make sure that

horribly misinterpet an error such as -ERESTARTSYS.

Due to a h/w bug on 8625 once cores come out of the low
power mode(GDFS) and immediately executing the first
"ldr" instruction causes the fetching of improper value
from the memory. This causes the aborts on cores. This
patch adds few memory read instrucitons before it actually

Currently snd_soc_jack_report() always acquires codec->mutex and
synchronize DAPM widgets. This automation is helpful if jack has defined
widget. However if codec driver doesn't have defined jack widget and
non-jack widget wants to synchronize with report_sock_jack's thread which
is usually irq handler, it can make dead-lock as all DAPM widget
call-backs are called after codec->mutex acquisition.
Add new API snd_soc_jack_report_no_dapm() so codec driver can have ability
of control DAPM synchronization part of snd_soc_jack_report()
