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:

quoted

+// Copyright (C) 2017 Jagan Teki [off-list ref]
+// SPDX-License-Indentifier: (GPL-2.0+ OR MIT)

Other way around. Make SPDX-License-Indentifier the first line.

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

Right. That was a common mistake or abiguity in the dts files. 

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!

I've been nuging folks to do that for a while now. Of course, now we 
need to go move the ids to the first line at some point.
