This is a note to let you know that I've just added the patch titled crypto: omap-sham - clear dma flags only after omap_sham_update_dma_stop() to the 5.14-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: crypto-omap-sham-clear-dma-flags-only-after-omap_sha.patch and it can be found in the queue-5.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c3f4c39ceb2e73eaaf1e31757681e980c8001209 Author: Tony Lindgren <tony@xxxxxxxxxxx> Date: Tue Jul 27 13:23:34 2021 +0300 crypto: omap-sham - clear dma flags only after omap_sham_update_dma_stop() [ Upstream commit fe28140b3393b0ba1eb95cc109f974a7e58b26fd ] We should not clear FLAGS_DMA_ACTIVE before omap_sham_update_dma_stop() is done calling dma_unmap_sg(). We already clear FLAGS_DMA_ACTIVE at the end of omap_sham_update_dma_stop(). The early clearing of FLAGS_DMA_ACTIVE is not causing issues as we do not need to defer anything based on FLAGS_DMA_ACTIVE currently. So this can be applied as clean-up.
