From: Jonathan Cameron Date: Sun, 8 May 2022 17:56:52 +0000 (+0100) Subject: iio: gyro: adis16080: Fix alignment for DMA safety X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ae6eeb534924ecc2afd5a394964fd6de0ca54d39;p=linux.git iio: gyro: adis16080: Fix alignment for DMA safety ____cacheline_aligned is an insufficient guarantee for non-coherent DMA on platforms with 128 byte cachelines above L1. Switch to the updated IIO_DMA_MINALIGN definition. Fixes tag is inaccurate but unlikely anyone will backport this beyond that point so I haven't chased the history futher than 2013.
