ALSA: hda - Preserve input pin-ctl bits in HP-automute for VIA codec
For smart51 pins, we need to preserve the input pin-control bits at auto-mute controls instead of overwriting zero or pin-out-only. Otherwise the VREF won't be set properly when smart51 is disabled again. Signed-off-by: Takashi Iwai <tiwai@suse.de>
