[alsa-devel] [PATCH 31/32] ASoC: wm9712: Cleanup manual bias level transitions

[Lars-Peter Clausen]

Set the CODEC driver's suspend_bias_off flag rather than manually going to
SND_SOC_BIAS_OFF in suspend. This makes the code a bit shorter and cleaner.

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.
