If anyone has any objections, please let me know. ------------------ From: Thorsten Blum commit 6b36f13891ab4709b7d60023005176cdd5c368cf upstream. Using sg_dma_len() is only valid after mapping a scatterlist with dma_map_sg(). However, starfive_aes_aead_do_one_req() uses it before mapping the scatterlist. Use the original scatterlist length because the DMA length has not been populated yet when CONFIG_NEED_SG_DMA_LENGTH=y.
