Subject[PATCH 3.13 105/163] drm/radeon: don't reset sdma on CIK init
Date
3.13.11.9 -stable review patch.  If anyone has any objections, please let me know.

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

From: Alex Deucher <alexander.deucher@amd.com>

commit 799028d5d85384cce140323be633c8d5f079193f upstream.

Otherwise we may lose the DMA golden settings which can
lead to hangs, etc.
