Subject: crypto: ux500 - memmove the right size
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.
