Subject: USB: fix PM config symbol in uhci-hcd, ehci-hcd, and xhci-hcd
From: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
commit f875fdbf344b9fde207f66b392c40845dd7e5aa6 upstream.
Since uhci-hcd, ehci-hcd, and xhci-hcd support runtime PM, the .pm
field in their pci_driver structures should be protected by CONFIG_PM
rather than CONFIG_PM_SLEEP. The corresponding change has already
been made for ohci-hcd.
Without this change, controllers won't do runtime suspend if system
suspend or hibernation isn't enabled.
