[PATCH v2 03/22] scsi: hisi_sas: relocate get_ata_protocol()
From: John Garry
Date: Thu May 25 2017 - 07:34:51 EST
From: Xiang Chen <chenxiang66@xxxxxxxxxxxxx>
Relocate get_ata_protocol() to a common location, as future
hw versions will require it.
Also rename with "hisi_sas_" prefix for consistency.
