Would this be OK?
static int sun4i_codec_handle_mic_bias_event(struct snd_soc_dapm_widget *w,
struct snd_kcontrol *k, int event)
{
struct sun4i_codec *scodec = snd_soc_card_get_drvdata(w->dapm->card);
if (SND_SOC_DAPM_EVENT_ON(event))
regmap_update_bits(scodec->regmap,
SUN4I_CODEC_ADC_ACTL,
BIT(SUN4I_CODEC_ADC_ACTL_VMICEN),
BIT(SUN4I_CODEC_ADC_ACTL_VMICEN));
else
regmap_update_bits(scodec->regmap,
SUN4I_CODEC_ADC_ACTL,
BIT(SUN4I_CODEC_ADC_ACTL_VMICEN),
0);
}
static const struct snd_soc_dapm_widget sun4i_codec_codec_dapm_widgets[] = {
...
SND_SOC_DAPM_MIC("Mic1", sun4i_codec_handle_mic_bias_event),
SND_SOC_DAPM_MIC("Mic2", sun4i_codec_handle_mic_bias_event),
Do I then remove
SND_SOC_DAPM_SUPPLY("VMIC", SUN4I_CODEC_ADC_ACTL,
SUN4I_CODEC_ADC_ACTL_VMICEN, 0, NULL, 0),
completely? What about the routes?
