From 1a4f69d5aaecb39a980fc20b14ec800fd5b53061 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 11 Sep 2014 15:22:46 +0200 Subject: [PATCH] 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.
