From 19ced623db2fe91604d69f7d86b03144c5107739 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 8 Jun 2016 14:56:39 +0200 Subject: [PATCH] crypto: ux500 - memmove the right size The hash buffer is really HASH_BLOCK_SIZE bytes, someone must have thought that memmove takes n*u32 words by mistake. Tests work as good/bad as before after this patch.
