Bug description:
[Impact]
We have a couple of lenovo laptops which have conexant codec, the
mute/mic-mute
doesn't work on these machines.
[Fix]
Without this patch, the generic driver will be in use for this codec, generic
driver doesn't apply any fixup for those machines, to let the led work, we
need
to apply fixup, so change the code to let patch_conexant.c drive hw.
[Test Case]
After booting up, please mute/mic-mute hotkeys, the led can turn on/off.
[Regression Risk]
Low. It is specific to the conexant codec with ID 1f86.
