From c75c66bbaa56f130e2be095402422e56f608aa62 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 1 Sep 2019 22:35:32 +0200 Subject: crypto: sha256 - Remove sha256/224_init code duplication 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.
