crypto: sun4i-ss - use crypto_ahash_digestsize
The size of the digest is different between MD5 and SHA1 so instead of using the higher value (5 words), let's use crypto_ahash_digestsize(). Signed-off-by: Corentin Labbe <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
