From 41ea0f6c19f6fa403370a9e40e4d500041eb4fc8 Mon Sep 17 00:00:00 2001 From: Tianjia Zhang Date: Mon, 20 Dec 2021 17:23:16 +0800 Subject: crypto: powerpc/sha - remove duplicate hash init function sha*_base_init() series functions has implemented the initialization of the hash context, this commit use sha*_base_init() function to replace repeated implementations.
