From 4eae4892c5bdef990b4b80997b813e2443d6554c Mon Sep 17 00:00:00 2001 From: Stefan Binding Date: Fri, 21 Jul 2023 16:18:12 +0100 Subject: 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.
