commit 694b14554d75f2a1ae111202e71860d58b434a21 upstream.
This control mute/unmute the ADC input of SGTL5000 using its CHIP_ANA_CTRL register.
This seems like a new feature and not an obvious candidate for stable?
there was a long email from Richard that said: Upstream commit 631bc8f0134a ("ASoC: sgtl5000: Fix of unmute outputs on probe"), which is e9f621efaebd in v5.3 replaced snd_soc_component_write with snd_soc_component_update_bits and therefore no longer cleared the MUTE_ADC flag. This caused the ADC to stay muted and recording doesn't work any longer. This patch fixes this problem by adding a Switch control for MUTE_ADC.
That's why I took this. If this isn't true, I'll be glad to drop this.
thanks,
