Hi,
this is a patch set as a follow up of the thread about the errors reported by kselftest mixer-test. It changes HD-audio and vmaster control behavior to return -EINVAL for invalid input values.
There is a change in kselftest itself to skip the write tests for volatile controls, too. It's for the channel map controls that can't hold the stable values.
