After a few 'interesting' issues due to the first patch in this series going in
as a fix, I have reapplied this patch to the togreg branch (pushed out for now
as testing) of iio.git. The prerequisits are now in place - note to anyone really
observant - this is why the iio.git togreg branch just got rebased.
