Hi Ivan,

Given I only wanted some trivial changes in patch 2, I've made those whilst applying
rather that wasting either of our time with a v6.  Please take a quick look to check
I didn't mess anything up!

Applied to the togreg branch of iio.git on kernel.org and pushed out as testing for
0-day to poke at it and see what it can find,

Thanks,

Jonathan
