Input: ad7879 - support auxiliary GPIOs via gpiolib
Drop the simple fancy sysfs hooks for the aux GPIOs and expose these via the gpiolib interface so that other drivers can use them. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
