ALSA: hda - Allow multiple callbacks for jack
So far, hda_jack infrastructure allows only one callback per jack, and this makes things slightly complicated when a driver wants to assign multiple tasks to a jack, e.g. the standard auto-mute with a power up/down sequence. This can be simplified if the hda_jack accepts multiple callbacks. This patch is such an extension: the callback-specific part (the function and private_data) is split to another struct from hda_jack_tbl, and multiple such objects can be assigned to a single hda_jack_tbl entry. The new struct hda_jack_callback is passed to each callback function now, thus the patch became bigger than expected. But these changes are mostly trivial. Signed-off-by: Takashi Iwai <tiwai@suse.de>
