huh, I guess not. That wasn't in my tree. I guess I should rebase.

Looking at it, my patch would have been preferable initially I think.
Each location of the additional checks in that patch first call
cam_mmap(), which I think is the most appropriate place to make the
decision.

I could do a replacement patch that reverts that one if preferred, or we
can leave it as is and I will drop this patch.
