Subject: [PATCH 01/19] scsi: hisi_sas: initialize dq spinlock before use
Date: Sat, 9 Dec 2017 01:16:32 +0800 [thread overview]
Message-ID: <1512753410-50924-2-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1512753410-50924-1-git-send-email-john.garry@huawei.com>
From: Xiang Chen <chenxiang66@hisilicon.com>
It is required to initialize the dq spinlock before use, which
was not being done, so fix it. This issue can be detected when
CONFIG_DEBUG_SPINLOCK is enabled.
