Those files are meant to be dual GPL 2.0 and GFDL without implicit sections. However, by a wrong cut-and-paste, I ended by applying a GPL 2+ license text to it, while still using the GPL 2.0 SPDX tag, with would cause an ambiguity about the licensing model. Solve this by explicitly mentioning that the dual licensing is between GPL 2.0 and GFDL and correcting the text. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
