This is a note to let you know that I've just added the patch titled dmaengine: stm32-mdma: fix chan initialization in stm32_mdma_irq_handler() 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: dmaengine-stm32-mdma-fix-chan-initialization-in-stm3.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 69e487b59142b5fdb3d94747e1710b56650c7c2b Author: Amelie Delaunay <amelie.delaunay@xxxxxxxxxxx> Date: Wed May 4 17:53:21 2022 +0200 dmaengine: stm32-mdma: fix chan initialization in stm32_mdma_irq_handler() [ Upstream commit da3b8ddb464bd49b6248d00ca888ad751c9e44fd ] The parameter to pass back to the handler function when irq has been requested is a struct stm32_mdma_device pointer, not a struct stm32_mdma_chan pointer. Even if chan is reinit later in the function, remove this wrong initialization.
