Subject: [PATCH] ALSA: hda - Fix HP/line-out initialization with IDT/STAC
codecs
It's possible that hp_detect is set even though no headphone pin is
detected. The driver issues, however, an unsol event only to hp_pins[0],
which can be invalid.
This patch adds the check of the valid pin to send an unsol event
at initialization and resume callbacks.
