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.
- SND_SOC_DAPM_PRE("MIC_BIAS_PRE", mic_bias_event),
- SND_SOC_DAPM_POST("MIC_BIAS_POST", mic_bias_event),
I don't understand what this is intended to do. The mic_bias_event() callback is already hooked up to the Mic Bias supply widget, it should be invoked whenever the bias is turned on and off already?
