From c1bf8ed3a5f3d011276d975c7b1f62039bed160e Mon Sep 17 00:00:00 2001

Subject: [PATCH 07/11] ALSA: hda: hda_component: Add pre and post playback
hooks to hda_component
These hooks can be used to add callbacks that would be run before and after
the main playback hooks. These hooks would be called for all amps, before
moving on to the next hook, i.e. pre_playback_hook would be called for
all amps, before the playback_hook is called for all amps, then finally
the post_playback_hook is called for all amps.
