Subject: [PATCH v6 04/22] scsi: hisi_sas: relocate get_ata_protocol()
Date: Wed, 14 Jun 2017 23:33:14 +0800	[thread overview]
Message-ID: <1497454412-91194-5-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1497454412-91194-1-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.
