Subject: drm/amdgpu: add check before free wb entry
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2d10c3dbde073ac005303b313d3e2cb99381eb6f;p=linux.git

drm/amdgpu: add check before free wb entry

Check if ring is not a mes queue before freeing the wb entry,
because we only allocate a wb entry when it's not a mes queue.
