Subject: [PATCH 3.13.y-ckt 079/139] drm/radeon: check the right ring in radeon_evict_flags()

3.13.11-ckt15 -stable review patch.  If anyone has any objections, please let me know.

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

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

commit 5e5c21cac1001089007260c48b0c89ebaace0e71 upstream.

Check the that ring we are using for copies is functional
rather than the GFX ring.  On newer asics we use the DMA
ring for bo moves.
