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

From: tom will <os@iscas.ac.cn>
commit 484f689fc9d4eb91c68f53e97dc355b1b06c3edb upstream.
When the initial value of i is greater than zero, it may cause endless loop, resulting in array out of bounds, fix it.
This is a port of the radeon fix to amdgpu.
