| Subject: crypto: ux500 - memmove the right size |
| |
| From: Linus Walleij <linus.walleij@linaro.org> |
| |
| 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. |
