VirtioCcwBusClass and VirtioPCIBusClass are both simple typedefs of VirtioBusClass (it's likely that I copied the ccw definition from the pci one). virtio-mmio instead uses VirtioBusClass directly in its checker macros. I don't see a real reason for the typedefs, maybe ccw and pci should use the mmio approach as well?
