Subject: [PATCH -next] crypto: qat - Use list_for_each_entry() helper
Date:   Wed, 30 Aug 2023 15:54:51 +0800
Message-ID: <20230830075451.293379-1-ruanjinjie@huawei.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

Convert list_for_each() to list_for_each_entry() so that the list_itr
list_head pointer and list_entry() call are no longer needed, which
can reduce a few lines of code. No functional changed.
