If the size of memory region that is being set up is the same as before,
we don't have to do memory and layer busy checks.

I'm not sure if this is semantically correct, but this helps to get
some old programs working, that rely on old DSS version which didn't
check for mmap lock, but incidentally they are using same size too..

Well, I wouldn't allow code like that if it was a new ioctl, but if, as
you say, the old omapfb worked that way, then I think it's better to do
things the same way.

I can see no harm in it, so I'll apply.
