ALSA: hda - Manage current pinctl values in generic parser
Use the new pin target accessors for managing the current pinctl values in the generic parser. The pinctl values of all active pins are once determined at the initialization phase, and stored via snd_hda_codec_set_pin_target(). This will be referred again in the codec init or resume phase to set the actual pinctl. This value is kept while the auto-mute. When a line-out or a speaker pin is muted by auto-mute, the driver simply disables the pin, but it doesn't touch the cached pinctl target value. Upon unmute, this value is used to restore the original pinctl in return. Signed-off-by: Takashi Iwai <tiwai@suse.de>
