From bb49d940344bcb8e2b19e69d7ac86f567887ea9a Mon Sep 17 00:00:00 2001 From: David Lechner dlechner@baylibre.com Date: Thu, 17 Apr 2025 11:52:37 -0500 Subject: [PATCH] iio: chemical: sps30: use aligned_s64 for timestamp MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit

Follow the pattern of other drivers and use aligned_s64 for the timestamp. This will ensure that the timestamp is correctly aligned on all architectures.
