I can't see why Rob would mind any of the changes made since he
Acked this (and having acked it I doubt he is looking at newer versions!)
so I'm going to take the view his Ack still applies.

Applied to the togreg branch of iio.git which will get pushed out first
as testing for the autobuilders to have a chance to play with it.

Thanks,

Jonathan
