Everything below can be dropped from this new file. Git has the most
accurate authority information.

I'm not sure why I added the authors-list in the first place to the
header when I implemented these functions as none of those folks have
contributed to this particular piece of work.

To summarize, I think this would be sufficient:

// SPDX-License-Identifier: GPL-2.0-only
/*

 * Copyright (C) 2014 Intel Corporation
 */

I think there should never be such a rush that acronym could not be
written with the correct spelling. I'm referring to 'tpm2' in the short
summary. I'm sorry, I had to say it, just can't help myself with those
kind of details :-) I can take care of fixing those once I apply these
patches.

You've done an awesome job. Thank you.

Unfortunately I'm not yet sure if I have time to test these before going
to Linux Plumbers but these would be anyway too close to the next merge
window to be added to the v5.4 PR.
