Rather than this long boilerplate, you might want to use the SPDX ids,
as started by Greg and documented by Thomas.
Noe that Linus wants the // comment style for the license line, and
since there is only two line left here I suggest using it for both
lines.
You can check also the recent doc patch posted by Thomas (tglx) and
comments from Linus and Greg.

So I guess you could use this:

> +// Copyright (C) 2017 Jagan Teki <jagan@...rulasolutions.com>
> +// SPDX-License-Indentifier: (GPL-2.0+ OR MIT)

NB: what you call X11 is has the MIT license id in the SPDX license list.

So you could replace 32 lines by only two lines :) it'[s neat right?

And this would also help as we have tagged already ~15K files, so it
would help to use this for new files so the amount of cleanup work
still left does not increase. Thank you for your kind consideration!
