Bug description:
  On one of Lenovo thinkcenter machines we have, there are two microphone jacks
  on the front panel, but only one of them can work after we plug a micrphone in

  Because two microphones are located in front panels, the alsa driver will 
  the same jack name to them, but pulseaudio can't handle two jacks with the 

  After applying this FIXUP, they will have different mixer name,
  then pulseaudio can handle them correctly.

  [Test Case]
  After booting up, plug micrphone into any one of the two audio jacks, the 
  works very well.

  [Regression Potential]
  Very low, since this patch is specific to the thinkcenter machine with 
subsystem id
