Hi Jonathan,

Did you have time to look at this?

Sorry, saw it go by but bad timing wrt to opening of merge window
so it was still in my 'to apply' queue.

Anyhow, now done so and it is in the fixes-togreg branch of iio.git +
marked for stable.

Note I'll probably rebase that tree after rc1 though as we have a few
other fixes I'd like in the same pull request for stuff that only
went in this cycle.

Thanks,

Jonathan
