With "Camera" do you mean some Maemo userspace application? Because I
think that nobody else could depends on gpio-switch kernel driver.

Anyway, it should be easy to rewrite such gpio-switch application to use
either input kernel events (from /dev/input/something) or directly check
gpio state via /sys/class/gpio/.

IIRC Maemo's Camera needed gpio-switch for testing if back camera cover
is open or closed and for checking when camera push button pressed and
released.
