Hi,

had to look up if i missed the newest trend but i did not ... :)

The sign-off is a simple line at the end of the explanation for the
patch, which certifies that you wrote it or otherwise have the right to
pass it on as an open-source patch.  The rules are pretty simple: if you
can certify the below:

        Developer's Certificate of Origin 1.1

        By making a contribution to this project, I certify that:

        (a) ...
        (b) ...
        (c) ...
	(d) ...

then you just add a line saying

	Signed-off-by: Random J Developer <random at developer.example.org>

using your real name (sorry, no pseudonyms or anonymous contributions.)

apart from that it looks sane will run this on a few arm boards today.
