The following ASoC codec drivers: sound/soc/codecs/rt5640.c sound/soc/codecs/rt5645.c
Use the following troublesome playback-switch-control names:
"Headphone Channel Switch" "HP Channel Switch" "Speaker Channel Switch"
There are 2 problems with these names:
1. They are the mute controls for the matching: "Headphone Playback Volume" "HP Playback Volume" "Speaker Playback Volume" controls, to be properly paired, which is necessary for HW volume-control support, the simple mixer code needs to recognize that the base-name for these is e.g. "Headphone" not "Headphone Channel".
2. They are playback-switches, yet they get recognized as global-switches.
Add these to the exceptions table so that they get the proper basename and type set.
Note we can NOT fix this by adding " Channel Switch" as a suffix to the suffixes table, because the line-out output on these codecs has the following controls:
"OUT Playback Switch" "OUT Channel Switch" "OUT Playback Volume"
Where the 2 switches describe mutes in 2 different places in the graph.
So if we were to add a " Channel Switch" suffix map to CTL_PLAYBACK_SWITCH then we would get 2 CTL_PLAYBACK_SWITCH controls for the "OUT" mixer element, which is not allowed.
