This patch had to be rebased on top of the current linux-next branch of the

Subject: PCI PCIe portdrv: Simplily probe callback of service drivers (rev. 2)
From: Rafael J. Wysocki <rjw@...k.pl>

The second argument of the ->probe() callback in
struct pcie_port_service_driver is unnecessary and never used.
Remove it.
