In order to preserve resolution of the microVolt value for existing code,
I'd prefer a solution similar to the existing implementation of
iio_read_channel_processed.   Sans error handling:

int uv;
if (iio_channel_has_info(chan->channel, IIO_CHAN_INFO_PROCESSED)) {
        int mv;
        iio_read_channel_processed(channel, &mv);
        uv = 1000 * mv;
} else {
        int raw;
        iio_read_channel_raw(channel, &raw);
        iio_convert_raw_to_processed(channel, raw, &uv, 1000);
}
return uv;
