Series applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to see if they can find anything we missed.

Thanks for persisting with this!  Note that it will be queued up for
next cycle and that I'll rebase my tree on rc1 once available.
I won't push out as togreg (which is picked up by linux-next) until
after that rebase.

Thanks,

Jonathan
