This is a note to let you know that I've just added the patch titled iio: adc: ti-ads124s08: Fix alignment for DMA safety to the 5.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: iio-adc-ti-ads124s08-fix-alignment-for-dma-safety.patch and it can be found in the queue-5.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 1427897712e7c3b4243eb02393aa7093f086a5d7 Author: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Date: Sun May 8 18:56:14 2022 +0100 iio: adc: ti-ads124s08: Fix alignment for DMA safety [ Upstream commit 7df19bd26cc0b85ff997cc9e2aaea712836b5460 ] ____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.
