Subject: [PATCH 0692/2940] drm/amdgpu: cleanup skipping IB test on KIQ
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Instead of hard coding the ring type in the function just never provide
a test_ib callback.
Additional to that remove the emit_ib callback to make sure the nobody
ever tries to execute an IB on the KIQ.
