I tested it and evtest gives back the right stuff with your patch. Can't test 
more because I have no headphone/mic here (I just inserted a screwdriver, 
grr). On 3.1 kernels, we also have no pin inversion, so unless Leon or Andrey 
(cc'ed) have different opinions, this can go through. Just give them a week...

Thanks!

Marc
