This patch works for me. When I enable runtime PM for both the root port and the host controller, and I see the xHCI host go into PCI runtime suspend, but there's no longer a message about the power state changing to D3cold. USB device connects while the PCI host is suspended work now, as well as remote wakeup. Tested-by: Sarah Sharp <sarah.a.sharp@xxxxxxxxxxxxxxx> Please mark this for stable.
