+Subject: [PATCH 173/194] 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.
