Subject: [PATCH 06/19] scsi: hisi_sas: modify hisi_sas_dev_gone() for reset
Date: Sat, 9 Dec 2017 01:16:37 +0800	[thread overview]
Message-ID: <1512753410-50924-7-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1512753410-50924-1-git-send-email-john.garry@huawei.com>

From: Xiang Chen <chenxiang66@hisilicon.com>

Do a couple of changes for when HISI_SAS_RESET_BIT is
set for HBA:
- Clearing ITCT is not necessary
- Remove internal abort as it will fail during reset

Flag sas_dev->dev_type is kept as SAS_PHY_UNUSED.
