commit bd886cdcbf9e746f61c74035a3acd42e9108e115 upstream.
Use correct argument to iio_str_to_fixpoint() to parse 3 decimal places.
iio_str_to_fixpoint() has a bit of an unintuitive API where the fract_mult parameter is the multiplier of the first decimal place as if it was already an integer. So to get 3 decimal places, fract_mult must be 100 rather than 1000.
