Bug Description

[Impact]
We plug a microphone in the audio jack, but the driver can't
detect the microphone and we try to record sound via this mic,
can't record any sound.

[Fix]
Backport one patch from upstream.

[Test]
Booting the patched kernel, open the gnome-sound-setting, plug a microphone,
we could see the system detect the microphone, and use this mic to record
sound, the sound is recorded successfully.

[Where problems could occur]
The change only applies to the specific machines with those SSIDs, it will
not introduce regression on other machines.
