A bit of an odd driver, somewhat similar to what Amazon described.
You register a PTP clock but there's no PTP involved. Also you call
pci_get_device() instead of binding to a proper bus.

Please repost this, add linux-pci and the PCI maintainers to the CC.
It'd be great to get their acks (in addition to Richard's).
