Public bug reported:
Since this patch is cced to stable kernel, I only send this patch
to oem-5.6 kernel, other ubuntu kernels will merge this patch with
stable update.
[Impact]
On a HP machine, if we plug a headset before booting, after booting
to the desktop, the mic can't be detected.
[Fix]
Realtek engineer submit a patch to usptream, I backport this patch
to ubuntu oem kernel.
[Test]
Plug a headset, then power on the machine, after entering the gnome,
check the mic, it is detected, and use mic to record, it could record
the sound.
[Regression Potential]
I could make the sound on that HP machine not work, but this possibility
is very low and this regression possibility is limited to this HP machine
since this patch use pin definition to apply the quirk.
