Frank Min 5aacf8917f drm/amdgpu: change non-dcc buffer copy configuration 
Without setting cpv bit and 7th ib dw, non-dcc buffer copy will have
random corruption

So set the cpv bit and clear the 7th ib dw for copy non-dcc buffers

Srinivasan Shanmugam e060c7ba7e drm/amdgpu: Remove duplicate check for *is_queue_unmap in sdma_v7_0_ring_set_wptr 
This commit removes a duplicate check for *is_queue_unmap in the
sdma_v7_0_ring_set_wptr function. The check at line 171 was considered
dead code because at this point in the code, we already know that
*is_queue_unmap is false due to the check at line 161.

By removing this unnecessary check, improves the readability of the
code

Fixes the below:
	drivers/gpu/drm/amd/amdgpu/sdma_v7_0.c:171 sdma_v7_0_ring_set_wptr()
	warn: duplicate check '*is_queue_unmap' (previous on line 161)
