Certainly. Now you've cleaned it up nicely it's ready
to go as far as I am concerned. I'll put together a patch
on top of this sometime in the next couple of days and
post to the relevant lists etc and if no one shouts I'll
send it in a pull request to Greg around next weekend....
Thanks for all your hard work!
Jonathan
(This patch is fine, I'll apply it to iio.git shortly.)
