iio: potentiostat: lmp91000: Fix alignment of buffer in iio_push_to_buffers_with_timestamp()
[ Upstream commit8979b67ec6
] 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. Fixes:67e17300dc
