| Subject: iio: potentiostat: lmp91000: Fix alignment of buffer in |
| iio_push_to_buffers_with_timestamp() |
| |
| 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. |
| |
