NAME
       usb_root_hub_lost_power - called by HCD if the root hub lost Vbus power

SYNOPSIS
       void usb_root_hub_lost_power(struct usb_device * rhdev);

ARGUMENTS
       rhdev
	   struct usb_device for the root hub

DESCRIPTION
       The USB host controller driver calls this function when its root hub is
       resumed and Vbus power has been interrupted or the controller has been
       reset. The routine marks rhdev as having lost power. When the hub
       driver is resumed it will take notice and carry out power-session
       recovery for all the “USB-PERSIST”-enabled child devices; the others
       will be disconnected.
