From 70d391a86317f77c30d4c0aa898b5fe0f75687b9 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 11 May 2023 12:29:36 +0800 Subject: [PATCH] crypto: lib/sha256 - Remove redundant and unused sha224_update The function sha224_update is exactly the same as sha256_update. Moreover it's not even used in the kernel so it can be removed.
