From f49282870fb039e3c2e5c3341bd27875282609d7 Mon Sep 17 00:00:00 2001 From: Tianjia Zhang Date: Mon, 21 Sep 2020 00:20:54 +0800 Subject: crypto: sm3 - export crypto_sm3_final function Both crypto_sm3_update and crypto_sm3_finup have been exported, exporting crypto_sm3_final, to avoid having to use crypto_sm3_finup(desc, NULL, 0, dgst) to calculate the hash in some cases.
