[PATCH 5.15 46/54] iio: adc: dln2: Use aligned_s64 for timestamp

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

[ Upstream commit 5097eaae98e53f9ab9d35801c70da819b92ca907 ]

Here the lack of marking allows the overall structure to not be
sufficiently aligned resulting in misplacement of the timestamp
in iio_push_to_buffers_with_timestamp(). Use aligned_s64 to
force the alignment on all architectures.
