I don't understand, what is the "root device"?
The hyper-v "bus controller"?

This shouldn't be a "raw" struct device, should it? It should be of a
type that shows exactly what it is. Is it a hyper_v device that talks
on the bus?
Or is it a "platform" device that controls all of the devices on the
bus, and as such should be the "root" device of the bus tree?
