[ Upstream commit b8f939fd20690623cb24845a563e7bc1e4a21482 ]
Add __aligned(8) to ensure the buffer passed to iio_push_to_buffers_with_timestamp() is suitable for the naturally aligned timestamp that will be inserted.
Here an explicit structure is not used, because this buffer is used in a non-trivial way for data repacking.
