From: Lars-Peter Clausen Date: Sat, 6 Sep 2014 12:29:35 +0000 (+0200) Subject: ASoC: sgtl5000: Cleanup bias level transitions X-Git-Tag: v3.18-rc1~99^2~8^2~1^2~8 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e649057a41c24b4122e976746649e471709d4b16;p=karo-tx-linux.git ASoC: sgtl5000: Cleanup bias level transitions Set the CODEC driver's suspend_bias_off flag rather than manually going to SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes the code a bit shorter and cleaner. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed.
