Hi!

Camera should work on N900, with v4.16-rc1. Autofocus should work;
flash is in the queue.

This patch is needed for non-square image. Patched v4l-utils is very
much recommened for taking photos.

Sakari: any ideas about this one? This is the bug I showed you in
Prague...

Best regards,
								Pavel
