Before this change iio_read_channel_processed_scale() always assumes that channels which advertise IIO_CHAN_INFO_PROCESSED capability return IIO_VAL_INT on success. Ignoring any fractional values from drivers which return IIO_VAL_INT_PLUS_MICRO / IIO_VAL_INT_PLUS_NANO. These fractional values might become non fractional after scaling so these should be taken into account for better precision. Use the new iio_multiply_value() helper to do proper scaling taking the fractionional values into account.
