Since there will be some changes to how iio_priv_to_dev() is implemented, it could be that the helper becomes a bit slower, as it will be hidden away in the IIO core. The iio_priv() call will still be fast enough, as it will return a void pointer from the public IIO device structure. So it's better to switch the order.
