Interestingly b4 isn't finding this tag.  I'm too lazy to look into why but
seems your email didn't reach patchwork either.
Applied it by hand whilst applying the patch to the togreg branch of iio.git
which given timing will be rebase on rc1 once available.  For now I'll just
push it out as testing to give 0-day a head start.
