No Signed-off-by?

Apparently Alistair Buxton, Rick L Vinyard Jr, and Thomas Berger were
involved with this code too. There's no mention of them in the commit

A few trivialities follow. And a question about the license of one of
these drivers.

Please indent the help text bit more (ie, add two spaces, like the help
texts of the rest of the added entries have).
