From 626abd3125e02d75e26f3cd2e2aa4a6fb74507b5 Mon Sep 17 00:00:00 2001 From: Corentin Labbe Date: Thu, 14 Nov 2019 11:58:13 +0100 Subject: [PATCH] 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().
