From: Matti Vaittinen Date: Mon, 3 Oct 2022 08:13:10 +0000 (+0300) Subject: iio: bmc150-accel-core: Use IIO_STATIC_CONST_DEVICE_ATTR() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c02b2a5166a58823e8a335c486ee71ce4f22f2b7;p=linux.git iio: bmc150-accel-core: 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.
