I don't think it is a bug, actually.

When the dm_root goes away the devices go away too since they are
no-longer accessible. Of course someone might still have a pointer to
a device that was active before the root went away. But I don't think
we should worry about devices that are implemented with static data.
That is not how things are supposed to be implemented.
