ALSA: hda - Restore cleared pin controls on resume
commit ac0547dc62e67a3e0b0c1628b6e49efba8f517db upstream.
Many codecs now clear the pin controls at suspend via snd_hda_shutup_pins()
for reducing the click noise at power-off. But this leaves some pins
uninitialized, and they'll be never recovered after resume.
This patch adds the proper recovery of cleared pin controls on resume.
Also it adds a check of bus->shutdown so that pins won't be cleared at
module unloading.
