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.

Regards
Sudip

Thanks for pointing this out! It's indeed quite a bug.
Going to send a patch ASAP.
