The fact that you don't send a real name in your patch submission mails
might be an issue here - I suspect you've fallen foul of spam filtering,
either automatic or human, there's no sign of this in my pending queue.

It would be better to make this an externally visible function (perhaps
just move it into the header with a regmap on the front of the name) so
that drivers can use this as part of the implementation of more complex
checks.  Otherwise this looks fine.
