Is this a follow through from the earlier 'correcting' the register
addresses?  Looks like it to me, so should really have been in that
same patch.

Oh well, it's staging and horribly broken so let's ignore that ;)

It's separated enough from the earlier patches that I will apply it now
though.  Applied to the togreg branch of iio.git and pushed out as
testing for the autobuilders to play with it.

Again I have added a do not backport note as far too much chance of
it going wrong.
