		What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
		When: November 2006
		Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
		more efficient. You should really be using libraw1394 for raw1394
		access anyway.
		Who: Jody McIntyre <scjody@modernduck.com>
		When: June 2007
		Why: Deprecated in favour of the more efficient and robust rawiso interface.
		Affected are applications which use the deprecated part of libraw1394
		(raw1394_iso_write, raw1394_start_iso_write, raw1394_start_iso_rcv,
		raw1394_stop_iso_rcv) or bypass libraw1394.
