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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
