I've debugged the kernel again after applying the fix in
698813ba8c58 ("ASoC: ops: Fix bounds check for _sx controls")
but it didn't fix the problem.
The commit message in your fix states this:
> For _sx controls the semantics of the max field is not the usual one, max
> is the number of steps rather than the maximum value. This means that our
> check in snd_soc_put_volsw_sx() needs to just check against the maximum
> value.
For some reason, this is not the case on my end.
Both the $platform_max and $max fields are set to the maximum value
of the range that is specified inside the codec code which is -84 to 40
and not the number of steps.
This was also the reason behind my patch to the bounds check.
