Philip Yang efcf063f8d drm/amdgpu: fix sdma v4 ring is disabled accidently ... For sdma v4, there is bug caused by commit d4e869b6b5d6 ("drm/amdgpu: add ring test for page queue")' local variable ring is reused and changed, so amdgpu_ttm_set_buffer_funcs_status(adev, true) is skipped accidently. As a result, amdgpu_fill_buffer() will fail, kernel message: [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off. [ 25.260444] [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off. [ 25.260627] [drm:amdgpu_fill_buffer [amdgpu]] *ERROR* Trying to clear memory with ring turned off.
