- * Modified in order to keep it compatible both with new and old videotext IOCTLs by
- * Michael Geng <linux@MichaelGeng.de>
- *
- * Cleaned up to use existing videodev interface and allow the idea
- * of multiple teletext decoders on the video4linux iface. Changed i2c
- * to cover addressing clashes on device busses. It's also rebuilt so
- * you can add arbitary multiple teletext devices to Linux video4linux
- * now (well 32 anyway).
- *
- * Alan Cox <alan@lxorguk.ukuu.org.uk>
- *
- * The original driver was heavily modified to match the i2c interface
- * It was truncated to use the WinTV boards, too.
- *
- * Copyright (c) 1998 Richard Guenther <richard.guenther@student.uni-tuebingen.de>
- *
- * Derived From
- *
- * vtx.c:
- * This is a loadable character-device-driver for videotext-interfaces
- * (aka teletext). Please check the Makefile/README for a list of supported
- * interfaces.
