I would not expect something called _BIAS_VOLT_SHIFT here.
Yes, the correct fix should be:
--- a/sound/soc/codecs/sgtl5000.c +++ b/sound/soc/codecs/sgtl5000.c @@ -1376,8 +1376,8 @@ static int sgtl5000_probe(struct snd_soc_codec *codec) sgtl5000->micbias_resistor << SGTL5000_BIAS_R_SHIFT);
snd_soc_update_bits(codec, SGTL5000_CHIP_MIC_CTRL, - SGTL5000_BIAS_R_MASK, - sgtl5000->micbias_voltage << SGTL5000_BIAS_R_SHIFT); + SGTL5000_BIAS_VOLT_MASK, + sgtl5000->micbias_voltage << SGTL5000_BIAS_VOLT_SHIFT); /* * disable DAP * TODO: Gianluca,
Care to send a v2 of the patch?
