[alsa-devel] [PATCH] ASoC: sgtl5000: fix powerup/down of micbias-voltage

[fischerc at swissphone.de]

From: Christian Fischer <fischerc at swissphone.de>

The mic-bias-voltage should get powered up/down automatically.
Added missing DAPM_PRE and DAPM_POST widgets to fire up the mic_bias_event function.

Signed-off-by: Christian Fischer <fischerc at swissphone.de>
