Hi Wolfson maintainers, hi Mark,
Recently, the wm9713 support broke on my platforms. I'm pretty sure that a
previous harmless warning became an error preventing the probe of my driver
(sound/soc/pxa/mioa701_wm9713.c) : the error is shown in [1] ("Control not
supported").
The warning "ASoC: no dapm match for Mic B Source" has be there as far as I'm
aware for ages, and it never prevented the probe before.
Now, if I apply the ugly patch in [2], everything works as expected ... but
that's definitely not the right fix.
Would any of you be able to figure out a fix please ?
Cheers.
