At the moment this will cause ppc64 to crash, since we rely on pci_dev->sysdata pointing to some node in the firmware device tree, either the device's node or the node for a parent bus.
We could change the ppc64 code to use pci_dev->bus->sysdata in the case when pci_dev->sysdata is NULL, which would fix the problem. I think that change should be incorporated as part of this patch so that we don't break git bisection.
In other words I don't want to see this patch applied as it stands.
