    USB: Add new PM callback methods for USB · f2189c47
    Alan Stern authored
    This patch (as1129) adds support for the new PM callbacks to usbcore.
    The new callbacks merely invoke the same old USB power management
    routines as the old ones did.
    
    A minor improvement is that the callbacks are present only in the
    "USB-device" device_type structure, rather than in the bus_type
    structure.  This way they will be invoked only for USB devices, not
    for USB interfaces.  The core USB PM routines automatically handle
    suspending and resuming interfaces along with their devices.
