Or I can pick this up after the merge window has closed if Greg hasn't

Did someone actually take this patch, or was it somehow lost?
I've picked it up now and applied it to the fixes-togreg branch of iio.git
Thanks for pointing out I'd forgotten it and sorry about that. I've also
marked it for stable.
