Could you use the new SPDX tags instead of this fine and long
boilerplate? See Thomas doc for details [1]

You could spare the world from ~14 lines of this fine legalese with this:

// SPDX-License-Identifier: GPL-2.0
// Copyright (C) 2012-2017 ARM Limited or its affiliates.

If you wonder about the C++ style comment, read Thomas doc patches [1]
and check the comments made on the list by Linus.

If you could spread the word out in your team too, this would be much welcomed!
Thanks!
