[SRU][OEM-5.10][PATCH 0/1] The front mic can't be detected on a lenovo thinkstation machine

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1937144

The patch is sent to oem-5.10 first, and other ubuntu kernels will
merge this patch with stable update since this patch was already
CCed to stable.

[Impact]
Users plug a headset or microphone to the front mic jack, but the
system can't detect the plug and will not set the mic to be the
active input device.

[Fix]
Backport a upstream patch, this will change the front mic jack's
name from Front Mic to Mic, then the pulseaudio could handle the
plug/unplug.

[Test]
Plug a headset to the front mic jack, open the gnome-sound-setting,
the front mic is the active input device, use this device to record
sound, it could record the sound successfully.


[Where problems could occur]
It could make the other mic can't be detected, but this possibility is
very low and I alreaed tested all audio jacks on that machine, all worked
well as before.
