Is this one a duplicate? I don't recall us being particular verbose
in terms of error messages in iio_triggered_buffer_setup_ext() which is
where that ends up coming from.  I think there is only one path
where it can return anything other than -ENOMEM and that one is a duplicate
registration check (so fair to not print).  So perhaps all this patch
needs is a comment on what errors can surface from this call and why
it is therefore not worth printing anything.
