Well, it's temporary in the sense "I have not added it back yet, but I commit to
add it back within 2 or 3 kernel cycles"

As for the confusion, I think the pxa_camera + mt9m111 set_crop() was not
working, but I didn't say that another camera host + mt9m111 didn't work. I
think set_crop() is not working because pxa_camera lacks code, but that doesn't
prevent mt9m111 to have a set_crop() sensor working implementation.

That's why I say I'm probably adding a regression, and commit to remove it soon
...

Cheers.
