In sdm660 due to change of notifier logic, there is a chance of
receiving only service down notifications during bootup. In this case
the initial boot flag is not cleared, as it is only cleared on
service up notification currenly.because of this, the next service down
event during SSR/PDR will be ignored. To fix this, clear initial boot flag
for both first service up/down notification, so that Reset notifications
are not ignored.

APR deregister is to be called for two ports from both
q6asm_callback(during RESET) and q6asm_audio_client_free.
In race condition between the two, APR deregister is called
only for one port. The mismatch in apr register-deregister
count causes apr not to reset service after ssr, causing
APR communication failure.

commit ab949d519601880fd46e8bc1445d6a453bf2dc09 upstream.
Imre Deak reported a deadlock of HD-audio driver at unbinding while
it's still in probing. Since we probe the codecs asynchronously in a
work, the codec driver probe may still be kicked off while the
controller itself is being unbound. And, azx_remove() tries to
process all pending tasks via cancel_work_sync() for fixing the other
races (see commit [0b8c82190c12: ALSA: hda - Cancel probe work instead
of flush at remove]), now we may meet a bizarre deadlock:
Unbind snd_hda_intel via sysfs:
device_release_driver() ->
device_lock(snd_hda_intel) ->
azx_remove() ->
cancel_work_sync(azx_probe_work)
azx_probe_work():
codec driver probe() ->
__driver_attach() ->
device_lock(snd_hda_intel)
This deadlock is caused by the fact that both device_release_driver()
and driver_probe_device() take both the device and its parent locks at
the same time. The codec device sets the controller device as its
parent, and this lock is taken before the probe() callback is called,
while the controller remove() callback gets called also with the same
lock.
In this patch, as an ugly workaround, we unlock the controller device
temporarily during cancel_work_sync() call. The race against another
bind call should be still suppressed by the parent's device lock.

I haven't come up with a good way to rewrite the code to avoid the

the conditionall initialization so gcc no longer has to worry about
it.
