No, I have no clue what is the right thing to in that error case. We have already plugged it once, so it should work (famous last words). - Independent of this patch, we check if hotplug_ctrl is NULL, but nothing else on the tree check for that. Ok, device_set_realize() check it, but nothing else, except network failover. I can't see how we are going to be able to arrive there and not having it, though. Later, Juan.
