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@amarulasolutions.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.

That's great: if you need some help there I have a tool that can help detect license and eventually inject a proper SPDX id [1] btw Thomas (tglx) posted a new patch set with the updated documentation.

Could it make sense, especially for new files, to avoid adding boilerplate that will need to be cleaned up later? You could get rid of these 37 lines and use this shorthand instead, using the new conventions started by greg-kh and documented by tglx? >> +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) >> +// Copyright (c) 2017 Jagan Teki <jagan@amarulasolutions.com> Thomas has sent a first doc patch [1] set and is working on an updated version. Jonathan also wrote a nice background article on the topic at LWN [2]. And as a bonus, this device tree addition of yours minus this boilerplate could save a few real trees if someone ever prints --god forbid-- this file, so you would be making a good thing for the planet! And consider too the energy savings from not having these extra bytes transferred million of times and not retrieved from disks spindles.
