Subject: [PATCH 3/4] crypto: hisilicon: Unify error detect process into qm
Date:   Mon, 20 Jan 2020 15:30:08 +0800
Message-ID: <1579505409-3776-4-git-send-email-tanshukun1@huawei.com>
In-Reply-To: <1579505409-3776-1-git-send-email-tanshukun1@huawei.com>
References: <1579505409-3776-1-git-send-email-tanshukun1@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-crypto-owner@vger.kernel.org
Precedence: bulk

In error detect process, a lot of duplicate code can put into qm. We add
two callback(get_dev_hw_err_status and log_dev_hw_err) into struct
hisi_qm_err_ini to handle device error detect, meanwhile the qm error
detect not changed.
