Subject: [PATCH 9/9] crypto: sha256 - Remove sha256/224_init code duplication
Date: Sun, 1 Sep 2019 22:35:32 +0200 [thread overview]
Message-ID: <20190901203532.2615-10-hdegoede@redhat.com> (raw)
In-Reply-To: <20190901203532.2615-1-hdegoede@redhat.com>
lib/crypto/sha256.c and include/crypto/sha256_base.h define
99% identical functions to init a sha256_state struct for sha224 or
sha256 use.
This commit moves the functions from lib/crypto/sha256.c to
include/crypto/sha.h (making them static inline) and makes the
sha224/256_base_init static inline functions from
include/crypto/sha256_base.h wrappers around the now also
static inline include/crypto/sha.h functions.
