You can also avoid making so many changes to usb_hcd_pci_probe() by registering your own probe routine in xhci-pci.c. Have it call usb_hcd_pci_probe() twice. You can add a new HCD_NO_RESOURCES flag bit, to prevent the various interrupt and memory resources from being allocated when the second hcd is registered.
