these two enumerated types are same for now. both of them might change in the future.
I have not used clang, but would .block_id = (int)head->block fix your warning? If such change is acceptable, I can make one then.
Thanks

Subject: Clang warning in drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c
Hi all,
The introduction of this file in commit dbd249c24427 ("drm/amdgpu: add amdgpu_ras.c to support ras (v2)") introduces the following Clang
warnings:

Normally, I would sent a fix for this myself but I am not entirely sure why these two enumerated types exist when one would do since they have the same values minus the prefix. In fact, the ta_ras_{block,error_type} values are never used aside from being defined. Some clarification would be appreciated.
Thank you,
Nathan
