This needs to be done differently:

../drivers/gpu/drm/amd/amdgpu/../powerplay/hwmgr/smu7_hwmgr.c:1344:12: error: 'smu7_reset_asic_tasks' defined but not used [-Werror=unused-function]

The function has no callers, so the easiest way would be to remove it
entirely, but it's possible that there are plans to add users soon.
