[PATCH 3.8 12/81] drm/radeon: forever loop on error in radeon_do_test_moves()

From: Kamal Mostafa
Date: Tue Oct 29 2013 - 14:24:42 EST -stable review patch. If anyone has any objections, please let me know.


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 89cd67b326fa95872cc2b4524cd807128db6071d upstream.

The error path does this:

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

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