The following ASoC codec drivers:
sound/soc/codecs/rt5659.c sound/soc/codecs/rt5660.c sound/soc/codecs/rt5665.c sound/soc/codecs/rt5668.c sound/soc/codecs/rt5670.c sound/soc/codecs/rt5682.c
Use the following troublesome capture-volume-control names: "IN1 Boost Volume" "IN2 Boost Volume" "IN3 Boost Volume" "STO1 ADC Boost Gain Volume" "STO2 ADC Boost Gain Volume" "Mono ADC Boost Gain Volume"
Note how these are suffixed with just " Volume" instead of "Capture Volume" add some special handling for this to the base_len() function, which is responsbile for getting the control-type, so that the type correctly gets set to CTL_CAPTURE_VOLUME instead of CTL_GLOBAL_VOLUME.
This correctly makes snd_mixer_selem_has_capture_volume() return true for these (and makes snd_mixer_selem_has_common_volume() return false).
