I've applied this to the togreg branch of iio.git, but not currently marked
it for stable. Primarily because it has been broken for a very long time.
If anyone wants this in stable, then feel free to shout out and we can send the
request to stable once it has merged.
Applied to the togreg branch and pushed out as testing for the autobuilders to
play with it.
Thanks,
Jonathan
