Hi Viresh,
I don't see anything in this patch that is specific to virtio-mmio, as
opposed to
virtio-pci. It would be better to move this into the virtio core code so it can
be called independently of the transport that is used for virtio.
The PCI code has similar code that will set vdev->dev.parent->of_node
for a virtio-pci device, as long as that node is present.
