Subject: [PATCH v3 04/12] iio: adc: ad_sigma_delta: use sizeof() in ALIGN()
Date: Tue, 01 Jul 2025 16:37:52 -0500 [thread overview]
Message-ID: <20250701-iio-adc-ad7173-add-spi-offload-support-v3-4-42abb83e3dac@baylibre.com> (raw)
In-Reply-To: <20250701-iio-adc-ad7173-add-spi-offload-support-v3-0-42abb83e3dac@baylibre.com>
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.
Suggested-by: Andy Shevchenko <andriy.shevchenko@intel.com>
