stable inclusion from stable-5.10.50 commit 1fa3107759b7ad44e8888529645c38616bdfd6db bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
