Subject: [PATCH v3 04/23] scsi: hisi_sas: relocate get_ata_protocol()
Date: Wed, 31 May 2017 22:32:56 +0800 [thread overview]
Message-ID: <1496241195-217678-5-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1496241195-217678-1-git-send-email-john.garry@huawei.com>
From: Xiang Chen <chenxiang66@hisilicon.com>
Relocate get_ata_protocol() to a common location, as future
hw versions will require it.
Also rename with "hisi_sas_" prefix for consistency.
