Subject: [ 27/69] drm/radeon: forever loop on error in radeon_do_test_moves()

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 89cd67b326fa95872cc2b4524cd807128db6071d upstream.

The error path does this:

	for (--i; i >= 0; --i) {

which is a forever loop because "i" is unsigned.
