Subject: [ 068/262] sound: tegra_alc5632: remove HP detect GPIO inversion

From: Greg KH <gregkh@...uxfoundation.org>

3.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stephen Warren <swarren@...dia.com>

commit c921928661eda599d73a6a86e58bdd5aecfa18cb upstream.

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.
