These files are licensed under GPL version 2 only. So use "GPL v2" instead of "GPL" (which means v2 or later). Also remove an empty (but commented) line at the end of the license header which nicely proves in the context that the drivers are really v2 only :-) Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>
