- if (!amdgpu_sriov_vf(adev) && (adev->gmc.xgmi.num_physical_nodes > 1)) {

That solution looks not optimal to me.
Checking adev->gmc.xgmi.num_physical_nodes > 1 already makes sure that
hive shouldn't be NULL.
If automated checkers complain about that we should probably drop the
adev->gmc.xgmi.num_physical_nodes > 1 check and check for hive instead.
