From 624664d15678f387c6e5c09b8148e5f29e76f80b Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 27 Jul 2021 13:23:34 +0300 Subject: [PATCH] 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.
