Subject: [PATCH 3/5] crypto: powerpc/sha - remove duplicate hash init function
Date: Mon, 20 Dec 2021 17:23:16 +0800	[thread overview]
Message-ID: <20211220092318.5793-4-tianjia.zhang@linux.alibaba.com> (raw)
In-Reply-To: <20211220092318.5793-1-tianjia.zhang@linux.alibaba.com>

sha*_base_init() series functions has implemented the initialization
of the hash context, this commit use sha*_base_init() function to
replace repeated implementations.
