Subject: [PATCH 06/11] scsi: hisi_sas: stop controller timer for reset
Date: Wed, 2 May 2018 23:56:29 +0800	[thread overview]
Message-ID: <1525276594-92173-7-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1525276594-92173-1-git-send-email-john.garry@huawei.com>

We should only have the timer enabled after PHY up after
controller reset, so disable prior to reset.
