ALSA: hda - Allow to enable/disable vmaster build explicitly
Another preliminary patch for the dual-codec support: since the support of vmaster over multiple codecs is difficult, simply disable it by a new flag to hda_codec struct. A new user hint is added as well for consistency. Signed-off-by: Takashi Iwai <tiwai@suse.de>
