Subject: ASoC: wm8960: Cleanup manual bias level transitions
X-Git-Tag: v3.19-rc1~119^2~20^2~3^3~1
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0a87a6e1c09c3b93d91bf65809e79cf6cf358785;p=karo-tx-linux.git

ASoC: wm8960: 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.
