Kernel test robot throws below warning ->

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:
In function 'dc_link_reduce_mst_payload':
   drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:3782:32:
warning: variable 'ret' set but not used [-Wunused-but-set-variable]
    3782 |         enum act_return_status ret;
