If this many people signed off on this, it better be correct :)

{sigh}

With all of those people, NO ONE ran checkpatch.pl on the thing?

I'm stopping here, please go do that, fix up the obvious issues it tells
you about (hint, no SPDX line and drop the huge license "boiler plate"
texts)

And also provide a REAL configuration help text, 4 words for this is
just not acceptable, what would you do if you were asked to review this?

thanks,
