Nitpick: Put your S-o-b last. Otherwise this ends as

	Sgned-off-by: Martin Blumenstingl <martin.blumenstingl@...glemail.com>
	Rviewed-by: Neil Armstrong <narmstrong@...libre.com>
	Sgned-off-by: Thierry Reding <thierry.reding@...il.com>

and this implies that Thierry added Neil's tag.  (Typos are done on
purpose to not confuse patchwork.)
