Subject: [PATCH] scsi: hisi_sas: Fix setting of hisi_sas_slot.is_internal
Date: Mon, 31 Jan 2022 19:13:27 +0800	[thread overview]
Message-ID: <1643627607-138785-1-git-send-email-john.garry@huawei.com> (raw)

The hisi_sas_slot.is_internal member is not set properly for ATA commands
which the driver sends directly. A TMF struct pointer is normally used as
a test to set this, but it is NULL for those commands. It's not ideal, but
pass an empty TMF struct to set that member properly.

Fixes: dc313f6b125b ("scsi: hisi_sas: Factor out task prep and delivery code")
Reported-by: Xiang Chen <chenxiang66@hisilicon.com>

Please consider this change for v5.17, thanks!
