From 4e63bca6e8c3a7fac800ee6c27f9afab13774fde Mon Sep 17 00:00:00 2001
From: Xiang Chen <chenxiang66@hisilicon.com>
Date: Fri, 9 Nov 2018 22:06:32 +0800
Subject: [PATCH 10/31] scsi: hisi_sas: Create separate host attributes per HBA
Origin: https://git.kernel.org/linus/c3566f9a617de3288739fd3b8e7539951bf2b04d
Currently all the three HBA (v1/v2/v3 HW) share the same host attributes.
To support each HBA having separate attributes in future, create per-HBA
attributes.
