OK, will replace with QCI, my bad.
And OK for all the other typos in pxa_camera.txt

As for the inline, I'm pretty sure you know it is automatically done by gcc.
As for moving it inside the loop, that would certainly improve performance. Yet
I find it more readable/maintainable that way, and will leave it. But I won't be
bothered at all if you retransform it back to your view, that's up to you.
Cheers.
