Subject: [PATCH 1/5] crypto: hisilicon/sec2 - clear SEC debug regs
Date: Fri, 26 Jun 2020 18:32:05 +0800 [thread overview]
Message-ID: <1593167529-22463-2-git-send-email-liulongfang@huawei.com> (raw)
In-Reply-To: <1593167529-22463-1-git-send-email-liulongfang@huawei.com>
From: Kai Ye <yekai13@huawei.com>
SEC debug registers aren't cleared even if its driver is removed,
so add a clearing operation in driver removing.
