From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
[ Upstream commit 8979b67ec61abc232636400ee8c758a16a73c95f ]
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 structure is not used, because this buffer is also used elsewhere in the driver.
