commit 40a9960b046290939b56ce8e51f365258f27f264 upstream.
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.
