Are you allowed to return 0 from this method ? Yes, but only _before_ the
device is connected to a channel. It could be argued that not being connected
to a channel is allowed only as a transient state during topology setup which
means that you should not return 0 _during_ simulation, because, honestly, an
unconnected device should not exist ever once you are past Simulator::Run.
Maybe what really makes sense here is to return 0 initially and a channel
pointer once the device has been successfully associated to its host device.
Does any of this matter ? I don't know: I merely pointed out something which
looked like a good idea to me. Feel free to ignore it.
