Hi Jonathan,
I don't know if it is an valid argument but when using tool "iio_info"
the temp_object wasn't displayed at all. After adding these two lines
the temp_object is displayed. Don't know if it is a problem with the
userspace tools.
iio_info version: 0.25 (git tag:b6028fde)
Libiio version: 0.25 (git tag: b6028fd) backends: local xml ip usb serial
Besides that it eases distinction between the two channels in the last
patch, but I think this argument is not strong enough. :)
Best regards,
Dimitri
