Aag. Whilst a correct fix, this is going to result in a userspace ABI
change. Driver has been in since 3.12. We may need to maintain
both ABI's for now and then deprecate it at some point. Easiest way to do this
will be to have two sets of iio_chan_specs pointing at the same underlying
real channels.
Anyone have a strong opinion about this?
Good spot by the way!
