Your patch is corrupted, but I've manually applied it.

I haven't marked it for stable because I worry a little that this will give
people unexpected changes in long term trends.  Better they see that only
on a major kernel version upgrade.

Applied to the fixes-togreg branch of iio.git.

Thanks,

Jonathan
