Jonathan et all,
Well actually this issues is in the build_channel_array function
located in iio_utils.c, but when testing my LIDAR driver with the
generic_buffer tool I found the following corner case.
So in_distance_* has a scale entry but no offset so it in turn it
fails.. at line 495 in iio_utils.c
Thanks,
Matt

This is odd. That line currently contains:
if ((ret < 0) && (ret != -ENOENT))
The -ENOENT bit is there to deal with the file not existing.
Any chance you are using a version prior to the fix that added the
ENOENT check?

tools: iio: make scale and offset files optional
from back on July.
There was a window in which it was broken prior to that.
