Applied to the togreg branch of iio.git
I wasn't sure if this one was technically a fix, but as it isn't
marked clearly as such it can go in during the next merge window.
I won't have pushed this out to a non rebasing branch until tomorrow
so if this fixes an observed issue then let me know and it might move
to the fixes-togreg branch.

Thanks,

Jonathan
