Subject: [PATCH] crypto: sun4i-ss: use crypto_ahash_digestsize
Date: Thu, 14 Nov 2019 11:58:13 +0100 [thread overview]
Message-ID: <20191114105813.13171-1-clabbe.montjoie@gmail.com> (raw)
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().
