Subject: [PATCH 3/4] scsi: libsas: Export sas_phy_enable()
Date: Tue, 12 Oct 2021 20:26:27 +0800 [thread overview]
Message-ID: <1634041588-74824-4-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1634041588-74824-1-git-send-email-john.garry@huawei.com>
From: Luo Jiaxing <luojiaxing@huawei.com>
Export sas_phy_enable(), so LLDDs can directly use it to control
remote phys.
We already do this for companion function sas_phy_reset().
