ALSA: hda - Merge HP mute-LED status callback on both IDT 92HD7x and 8x codecs
Merge the mute-LED status callback function for both IDT 92HD7x and 8x codecs to one function. Also it's changed to check all DACs, and called in the initialization to sync with the current status. Signed-off-by: Takashi Iwai <tiwai@suse.de>
