[PATCH 1/2] drm/amdgpu: potential uninitialized variable in amdgpu_vce_ring_parse_cs()
We shifted some code around in commit 9cca0b8e5df0 ("drm/amdgpu: move amdgpu_cs_sysvm_access_required into find_mapping") and now my static checker complains that "r" might not be initialized at the end of the function. I've reviewed the code, and that seems possible, but it's also possible I may have missed something.
