From: Ovidiu Panait Date: Mon, 19 May 2025 15:13:48 +0000 (+0300) Subject: crypto: sun8i-ce - fix nents passed to dma_unmap_sg() X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b6cd3cfb5afe49952f8f6be947aeeca9ba0faebb;p=thirdparty%2Fkernel%2Fstable.git crypto: sun8i-ce - fix nents passed to dma_unmap_sg() In sun8i_ce_cipher_unprepare(), dma_unmap_sg() is incorrectly called with the number of entries returned by dma_map_sg(), rather than using the original number of entries passed when mapping the scatterlist. To fix this, stash the original number of entries passed to dma_map_sg() in the request context.
