From cb2510dac7e1c5ac77652bb31e8c39ce2eef8bbe Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sun, 19 Jul 2015 12:15:17 +0200 Subject: ASoC: cs4349: Fix suspend/resume dev_get_drvdata() will not return the snd_soc_runtime to which this CODEC is attached, so the current code will result in undefined behavior. To fix this just use regmap_update_bits(cs4349->regmap, ...) directly instead of snd_soc_update_bits(rtd->codec, ...).
