(But I also spotted this line. And then I checked 2/2, which has:
This patch is dependent on PATCH V1 1/2
Which makes it all rather confusing.
Anyhow, neither patch should need to carry such a line. The 1/2 and 2/2
in the Subject: line should suffice.)

And (according to include/linux/module.h) this states the license is

How can there be dependencies between a binding document and a driver

It's wrong to mention platform data here. Just tell us what the
property is for.

I feel like you're burying the dlg,disable-key-power documentation in
side a long winded paragraph. It's better to start the line with it,
like:

I am using a git format-patch to generate the patches but our in-house IT
department complications disallow the use of git send-email.

okay, I'll make that change.
Thanks for the comments,
I'll send PATCH V2 after I make the changes requested by yourself and Paul Bolle
(see https://lkml.org/lkml/2015/4/9/150).

My reading comprehension is declining. Because I only now noticed that
the comment at the top of this file states the license is LGPL v2 or
later (note the L).
Grepping the tree for "Library General" gave over 100 hits, a few of
them even in drivers/, so I suppose LPGL v2 is fine for the kernel. It
_feels_ a bit odd to use it for a driver, but that might just be me.
