drm/amdgpu: Potential uninitialized variable in amdgpu_vm_update_directories()
After commit ea09729c9302 ("drm/amdgpu: rework page directory filling v2") then it becomes a lot harder to verify that "r" is initialized. My static checker complains and so I've reviewed the code. It does look like it might be buggy... Anyway, it doesn't hurt to set "r" to zero at the start.
