From 1a913da6cfda0139bfe1fe203858d5ba30ac853d Mon Sep 17 00:00:00 2001 From: David Lechner Date: Tue, 1 Jul 2025 16:37:52 -0500 Subject: [PATCH] iio: adc: ad_sigma_delta: use sizeof() in ALIGN() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Use sizeof() instead of hardcoding the size of the timestamp in the ALIGN() macro. This makes it a bit more obvious what the intention of the code is.
