drivers/gpu/drm/amd/amdgpu/../pm/powerplay/kv_dpm.c:1678:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/amdgpu/../pm/powerplay/kv_dpm.c: In function ‘kv_dpm_powergate_vce’:
drivers/gpu/drm/amd/amdgpu/../pm/powerplay/kv_dpm.c:1706:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]
