From 1c325f771a88579f227fe017e4ee77d852cf5435 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 4 Sep 2014 19:44:05 +0200 Subject: [PATCH] ASoC: Shutdown DAPM contexts when removing a card Currently when a ASoC sound card is unregistered we leave the individual components in their current state, just call the remove() callback and leave it to the drivers to do the proper shutdown/cleanup. This patch introduces a call to snd_soc_dapm_shutdown() when removing the card. This will make sure that all DAPM widgets are properly powered down and all DAPM contexts are put at the SND_SOC_BIAS_OFF level. This will ensure that all components are properly powered down when the card is removed. Since a lot of drivers manually go to SND_SOC_BIAS_OFF in their remove callback this will also allow us to remove a bit of duplicated code.
