camera on n900, v4.8
Hi!
Camera has some non-trivial dependencies on N900; it seems to rely on gpio-switch.c, for example. I'll try to strip the diff further, but in the meantime, here's the version I'm working with.

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.

With camera, I mean kernel drivers for /dev/video*. I don't know why they depend on gpio-switch.c, but they do.
I'm using fcam-dev for userspace control of camera. I'd prefer not to touch anything w/o sources.
