From 2f396a91d1d01a423fd87b7c6ff71600d06b9c05 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 18 Oct 2015 17:24:11 +0100 Subject: [PATCH] crypto: marvell/cesa - always ensure mid-fragments after first-fragment If we add a template first-fragment operation, always update the template to be a mid-fragment. This ensures that mid-fragments always follow on from a first fragment in every case. This means we can move the first to mid-fragment update code out of mv_cesa_ahash_dma_add_data().
