[ALSA] hda-codec - optimize resume using caches
So far, the driver looked the table of snd_kcontrol_new used for creating mixer elements and forces to call each of its put callbacks in PM resume code. This is too ugly and hackish. Now, the resume is simplified using the codec amp and command register caches. The driver simply restores the values that have been written in the cache table. With this simplification, most codec support codes don't require any special resume callback. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
