Have you considered using the new SPDX ids? Something like this:

// SPDX-License-Identifier: GPL-2.0
// Copyright (c) 2013-2015, The Linux Foundation. All rights reserved.

Beside  being simpler and increasing the code to comment ratio by
deleting 9 lines of boilerplate, this will also save a few trees over
the long term each time that I print the source code of the kernel ;)
(do not worry, I am NOT as insane as to really print the kernel
sources, but someone more insane than me may well do it)

You may wonder about the C++ // comment style I used here... Please
see Linus posts on the topic as well as Thomas doc patches overall for
instructions on using the SPDX ids.

And if you were to do this for your past, present and future
contributions (eventually these of your group), I would be quite
grateful.

Thank you for your kind consideration
