[PATCH v2 0/6] ALSA: some driver fixes for control input validations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

this is a revised 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 verification after
write tests for volatile controls, too.  It's for the channel map
controls that can't hold the stable values.

v1->v2:
* Skip only verification after write in kselftest
* Add sanity check to HDMI chmap write, too
