From e1620d591a75a10b15cf61dbf8243a0b7e6731a2 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 18 Mar 2011 19:55:36 +0100 Subject: [PATCH] USB: Move runtime PM callbacks to usb_device_pm_ops USB defines usb_device_type pointing to usb_device_pm_ops that provides system-wide PM callbacks only and usb_bus_type pointing to usb_bus_pm_ops that provides runtime PM callbacks only. However, the USB runtime PM callbacks may be defined in usb_device_pm_ops which makes it possible to drop usb_bus_pm_ops and will allow us to consolidate the handling of subsystems by the PM core code.
