This one deserves a 'woot' :)

I would have guessed we were much further off being able to do this
than the 18 patches earlier in this series. Good work from Andy
and yourself to get to the point where this was possible.

Applied to the togreg branch of iio.git and pushed out as testing for
0-day to take a look.  I'm probably going to review the remainder, but
leave on list a bit longer as they are more complex/controversial than
this includes cleanup.

Thanks,

Jonathan
