[alsa-devel] [PATCH] ASoC: jack: export gpio detect

From: Christopher Freeman <cfreeman at nvidia.com>

Export the gpio detect function so machine drivers
may call it.  Interrupts for the jack may be disabled
during sleep, so this allows a machine driver to have
the jack status updated during resume.
