From f7e6804509eeb27accc6625150db3f02d0b93ad7 Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Mon, 3 Oct 2022 11:12:48 +0300 Subject: [PATCH] iio: adxl372: Use IIO_STATIC_CONST_DEVICE_ATTR() Slightly simplify by dropping open-coded constant data iio_dev_attr functions and using the IIO_STATIC_CONST_DEVICE_ATTR() instead.
