Subject: ALSA: hda - change the location for one mic on a Lenovo machine

From: Hui Wang <[email protected]>

commit 8da5bbfc7cbba909f4f32d5e1dda3750baa5d853 upstream.

There are two front mics on this machine, and current driver assign the same name Mic to both of them, but pulseaudio can't handle them. As a workaround, we change the location for one of them, then the driver will assign "Front Mic" and "Mic" for them.
