This is a note to let you know that I've just added the patch titled iio: magn: rm3100: Fix alignment of buffer in iio_push_to_buffers_with_timestamp() to the 5.13-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-magn-rm3100-fix-alignment-of-buffer-in-iio_push_.patch and it can be found in the queue-5.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 422c39a2fc017a5898f2c77981cf135ee59b5622 Author: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx> Date: Sun Jun 13 16:22:58 2021 +0100 iio: magn: rm3100: Fix alignment of buffer in iio_push_to_buffers_with_timestamp() [ Upstream commit b8f939fd20690623cb24845a563e7bc1e4a21482 ] Add __aligned(8) to ensure the buffer passed to iio_push_to_buffers_with_timestamp() is suitable for the naturally aligned timestamp that will be inserted. Here an explicit structure is not used, because this buffer is used in a non-trivial way for data repacking.
