> Subject: [PATCH 7/7] drm/amdgpu: Remove redundant .ras_late_init
> initialization in some ras blocks
>
> 1. Define amdgpu_ras_block_late_init_default in amdgpu_ras.c as
> .ras_late_init common function, which is called when
> .ras_late_init of ras block doesn't initialize.
[Tao]: doesn't initialize -> "isn't initialized" or "is uninitialized"
> 2. Remove the code of using amdgpu_ras_block_late_init to
> initialize .ras_late_init in ras blocks.
