| Subject: iio: chemical: atlas: Fix buffer alignment in |
| iio_push_to_buffers_with_timestamp() |
| |
| From: Jonathan Cameron <Jonathan.Cameron@huawei.com> |
| |
| [ Upstream commit b0f5d8db7348a6ce5cdd79fba46ebc91eebc8fd9 ] |
| |
| Variable location for the timestamp, so just use __aligned(8) |
| to ensure it is always possible to naturally align it. |
| |
| Found during an audit of all calls of uses of |
| iio_push_to_buffers_with_timestamp() |
| |
| Fixes tag is not accurate, but it will need manual backporting beyond |
| that point if anyone cares. |
| |
| Fixes: 0d15190f53b4 ("iio: chemical: atlas-ph-sensor: rename atlas-ph-sensor to atlas-sensor") |
