From: Lars-Peter Clausen Date: Sun, 23 Nov 2014 12:37:41 +0000 (+0100) Subject: ASoC: wm8991: Cleanup manual bias level transitions X-Git-Tag: v3.19-rc1~11^2~38^2~1^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=497b900f83c56d513794ccf56b7a87c50a34a454;p=platform%2Fkernel%2Flinux-exynos.git ASoC: wm8991: Cleanup manual 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.
