 /* elmcan.c - ELM327 based CAN interface driver
  *            (tty line discipline)
  *
- * This file is derived from linux/drivers/net/can/slcan.c
+ * This driver started as a derivative of linux/drivers/net/can/slcan.c
+ * and my thanks go to the original authors for their inspiration.
  *
  * elmcan.c Author : Max Staudt <max-linux@enpas.org>
  * slcan.c Author  : Oliver Hartkopp <socketcan@hartkopp.net>
  * slip.c Authors  : Laurence Culhane <loz@holmes.demon.co.uk>
  *                   Fred N. van Kempen <waltje@uwalt.nl.mugnet.org>
  *
+ * This code barely bears any resemblance to slcan anymore, and whatever
+ * may be left is Linux specific boilerplate anyway, however I am leaving
+ * the GPL-2.0 identifier at the top just to be sure.
+ *
+ * Please feel free to use my own code, especially the ELM327 communication
+ * logic, in accordance with SPDX-License-Identifier BSD-3-Clause to port
+ * this driver to other systems.
