- ehci_lpm_check and ehci_lpm_set_da are only used in ehci_update_device
defined in drivers/usb/host/ehci-pci.c.
- ehci_adjust_port_wakeup_flags (disguised as
ehci_prepare_ports_for_controller_suspend and
ehci_prepare_ports_for_controller_resume) are only used in drivers that
support suspend and resume. Not all do.
