I'm a bit lost on which of us is asking for what and can't figure it out
from the patch history.  Anyhow, I did make one tweak whilst applying -
I think some confusion occurred as I don't think we'd disagree on this one
and you called it out in an earlier review.

It's only just over 80 chars and flipping to 
		if (!data->chip_info->sensitivity_avail[i])
			continue;
		len += sysfs_emit_at(..

doesn't seem worth the effort.
 
With that applied to the testing branch of iio.git.

Thanks,
