ASoC: rt5670: Remove ADC vol-ctrl mute bits poking from Sto1 ADC mixer settings
The SND_SOC_DAPM_MIXER declaration for "Sto1 ADC MIXL" and "Sto1 ADC MIXR" was using the mute bits from the RT5670_STO1_ADC_DIG_VOL control as mixer master mute bits. But these bits are already exposed to userspace as controls as part of the "ADC Capture Volume" / "ADC Capture Switch" control pair: SOC_DOUBLE("ADC Capture Switch", RT5670_STO1_ADC_DIG_VOL, RT5670_L_MUTE_SFT, RT5670_R_MUTE_SFT, 1, 1), SOC_DOUBLE_TLV("ADC Capture Volume", RT5670_STO1_ADC_DIG_VOL, RT5670_L_VOL_SFT, RT5670_R_VOL_SFT, 127, 0, adc_vol_tlv), Both the fact that the mute bits belong to the same reg as the vol-ctrl and the "Digital Mixer Path" diagram in the datasheet clearly shows that these mute bits are not part of the mixer and having 2 separate controls poking at the same bits is a bad idea. Remove the master-mute bits settings from the "Sto1 ADC MIXL" and "Sto1 ADC MIXR" DAPM widget declarations, avoiding these bits getting poked from 2 different places. This should not cause any issues for userspace. AFAICT the rt567x codecs are only used on x86/ACPI devices and the UCM profiles used there already set the "ADC Capture Switch" as needed.
