Hi Gerald,

Looks good to me (thanks to Andy for his work reviewing!)

Unfortunately timing is such that we are too close to the merge window, so
I'm not planning on doing another pull request for this cycle. As such it's
the first thing I've queued up for 6.3.

Applied to the togreg branch of iio.git and pushed out as testing for
0-day to take a look at it.

Note I'll probably rebase the tree after rc1 and so it won't push out as
togreg (which is meant to be non-rebasing) until after that point.

Thanks,

Jonathan
