So couple of general things for future reference.
1. New versions of a patch need a title such as [PATCH V2]
2. You have several similar patches, they would have been best sent
   as a series as that lets a maintainer pick them all up in one go.
3. Don't send new versions in reply to older versions.  It doesn't scale
   as we regularly end up 10 or more versions in to a series.  Not to mention
   many reviewers read backwards in time (as often earlier patches are resolved
   before you get to them) so by sending it as a reply you ensured it was much
   less likely to be applied.  Here you were luck as I am on holiday so have
   time to catch up.

Applied to the togreg branch of iio.git with the message above tidied up
a little.  Will be pushed out as testing for the autobuilders to poke at it.

Thanks,

Jonathan
