Subject: [PATCH 2/2] drm/amdgpu: clean up UVD instance handling v2
The whole handle, filp and entity handling is superfluous here.
We should have reviewed that more thoughtfully. It looks like somebody just made the code instance aware without knowing the background.
v2: fix one more missed case in amdgpu_uvd_suspend
