[ Upstream commit bae028e3e521e8cb8caf2cc16a455ce4c55f2332 ]
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_atombios.c: In function
'amdgpu_atombios_get_connector_info_from_object_table':
drivers/gpu/drm/amd/amdgpu/amdgpu_atombios.c:376:26: warning: variable
'grph_obj_num' set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/amdgpu/amdgpu_atombios.c:376:13: warning: variable
'grph_obj_id' set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/amdgpu/amdgpu_atombios.c:341:37: warning: variable
'con_obj_type' set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/amdgpu/amdgpu_atombios.c:341:24: warning: variable
'con_obj_num' set but not used [-Wunused-but-set-variable]
They are never used, so can be removed.
