Subject: [PATCH 07/23] scsi: hisi_sas: only reset link for PHY_FUNC_LINK_RESET
Date: Thu, 23 Mar 2017 01:25:23 +0800	[thread overview]
Message-ID: <1490203539-228029-8-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1490203539-228029-1-git-send-email-john.garry@huawei.com>

We currently do a hard reset for a link reset. Change this
to do a link reset only.
