Subject: [PATCH 3.4 054/176] drm/radeon: check the right ring in radeon_evict_flags()

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

3.4.107-rc1 review patch.  If anyone has any objections, please let me know.

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


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.
