I've been in a bit of a mess due to travel etc, so
more than possible I hadn't pushed it out as I should have
done.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git/commit/?h=fixes-togreg&id=1244a720572fd1680ac8d6b8a4235f2e8557b810

I didn't see this before I'd pushed out for Arnd's patch hence
not sure if it was there before or not!

Sorry about that,

Jonathan
