[PATCH 4.4 16/32] crypto: ux500 - memmove the right size
From: Greg Kroah-Hartman
Date: Wed Jul 06 2016 - 21:27:25 EST
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Walleij <linus.walleij@xxxxxxxxxx>
commit 19ced623db2fe91604d69f7d86b03144c5107739 upstream.
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.
