Public bug reported:
This fix is only for oem-5.6 kernel, other kernels will merge this
patch with stable update. Our oem project needs this patch to be merged
ASAP.
[Impact]
When using a HP machine, after plugging the headset at front jack,
there is no any input device shows.
[Fix]
The codec of the HP ZCentrol is alc671 and it needs to override the pin
configuration to enable the headset mic.
This patch is going to be merged by upstream, now backport it to
oem-5.6 kernel.
[Test Case]
Boot the system, plug a headset and check the gnome-control-center,
the Mic is active in the UI, and record the sound, it could record
the sound.
[Regression Risk]
Low, this patch is to add a platform specific quirk to override pin
configuration and already tested in this HP machine.
