Hi All,

The builds of arm64 allmodconfig with clang failed to build next-20220920
with the error:

drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c:1190:3: error: variable 'r' is uninitialized when used here [-Werror,-Wuninitialized]
                r |= !amdgpu_ttm_tt_get_user_pages_done(bo->tbo.ttm);
                ^
drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c:1171:7: note: initialize the variable 'r' to silence this warning
        int r;
             ^
              = 0
1 error generated.


git bisect pointed to c2b08e7a6d27 ("drm/amdgpu: move entity selection and job init earlier during CS")

I will be happy to test any patch or provide any extra log if needed.
