Subject: Clang warning in drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c
Date: Tue, 19 Mar 2019 17:54:06 -0700 [thread overview]
Message-ID: <20190320005406.GA16412@archlinux-ryzen> (raw)
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:
drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:544:23: warning: implicit conversion from enumeration type 'enum amdgpu_ras_block' to different enumeration type 'enum ta_ras_block' [-Wenum-conversion]

6 warnings generated.
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
