> Subject: [PATCH] drm/amdgpu: fixed the warnings reported by kernel test robot
> 
> The reported warnings are as follows:
>   1.warning:no-previous-prototype-for-amdgpu_hdp_ras_fini.
>   2.warning:no-previous-prototype-for-amdgpu_mmhub_ras_fini.
> 
> Amdgpu_hdp_ras_fini and amdgpu_mmhub_ras_fini are unused in the code,
> they are the only functions in amdgpu_hdp.c and amdgpu_mmhub.c. After
> removing these two functions, both amdgpu_hdp.c and amdgpu_mmhub.c are
> empty, so these two files can be deleted to fix the warning.
