Subject: [PATCH 13/19] scsi: hisi_sas: use an general way to delay PHY work
Date: Sat, 9 Dec 2017 01:16:44 +0800 [thread overview]
Message-ID: <1512753410-50924-14-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1512753410-50924-1-git-send-email-john.garry@huawei.com>
From: Xiaofei Tan <tanxiaofei@huawei.com>
Use an general way to do delay work for a PHY. Then it will
be easier to add new delayed work for a PHY in future.
