ALSA: hda - Add EAPD control to Conexnat auto-parser
Added the vmaster hook for controlling EAPD dynamically to Conexant auto-parser. When the Master is muted, EAPDs are turned off as well. This will fix the missing mute-LED control on some machines in addition to the more power-saving in the auto-parser mode. Signed-off-by: Takashi Iwai <tiwai@suse.de>
