This patch (as1023) updates the code in usb_reset_composite_device():

	Some local variable declarations are moved to inner loops.

	The interface locks are not acquired.  This isn't necessary
	any more; its only reason was to prevent an interface from
	being suspended or resumed during the reset.  But now
	interface power management is controlled by the USB device
	lock, not by the interface lock.

	The check for whether the interface is registered is removed.
	There doesn't seem to be any reason for checking; a driver
	for a non-registered interface deserves to be informed of
	device resets just as much as any other.
