Whilst sashiko did have quite a lot to say I 'think' they are all fine.
However, please do take a look and if you disagree then shout.

It may well be there are things in there that should be patches on top anyway.
I think all but 1 were things it even thought were preexisting issues.
Anyhow applied to the testing branch of iio.git which i just rebased
