I'm not sure I see the point of this, I would expect that a failure to
probe or the removal of the device would leave the xenbus state as
closed, which is consistent with the actual driver state.

Can you explain what's the benefit of leaving a device without a
driver in such unknown state?

Thanks, Roger.
