[PATCH] sound: tegra_alc5632: remove HP detect GPIO inversion

[Stephen Warren]

From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Both the schematics and practical testing show that the HP detect GPIO
is high when the headphones are plugged in. Hence, the snd_soc_jack_gpio
should not specify to invert the signal.

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
