The point is that the removal should not happen in the first place.
Though it seems that even a held refcount on the module is not
preventing that, which is bad to begin with.
That aside I'm not saying that supporting removal is completely
impossible. The charger driver can probably be fixed, but as this is a
user space visible change this needs a lot of thoughts and proper
analysis why such a change would be correct under all circumstances.
