[ALSA] hda-codec - Add a generic bind-control helper
Added callbacks for a generic bind-control of mixer elements. This can be used for creating a mixer element controlling multiple widgets at the same time. Two macros, HDA_BIND_VOL() and HDA_BIND_SW(), are introduced for creating bind-volume and bind-switch, respectively. It taks the mixer element name and struct hda_bind_ctls pointer, which contains the real control callbacks in ops field and long array for private_value of each bound widget. All widgets have to be the same type (i.e. the same amp capability). Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
