-Subject: [PATCH] ASoC: tlv320aic32x4: SND_SOC_DAPM_MICBIAS is
- deprecated
-
-commit 04d979d7a7bac2f645cd827ea37e5ffa5b4e1f97 upstream.
-
-SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY.
-
-MICBIAS voltage wasn't supplied to the microphone with the older
-SND_SOC_DAPM_MICBIAS widget, hence the microphone wouldn't work.
-
-This patch fixes the problem.
