[ALSA] hda-codec - Fix wrong pin-setup at resume of STAC codecs
The resume procedure for STAC codecs overrides the cached values and results in the wrong (reset) PIN state. The patch gets rid of the overriding part and simplifies the resume. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
