sys/dev/usb/usbdi_util.h not protected from multiple includes ?

[Luigi Rizzo]

Just noticed (on stable while building a kernel module, but this
affects current as well) that  sys/dev/usb/usbdi_util.h is
not protected from multiple includes - i.e. it doesn't have
the

	#ifndef _USBDI_UTIL_H
	#define _USBDI_UTIL_H
	...
	#endif

wrapper around it.
Any objection if i commit it ?

	cheers
