Subject: [PATCH v2 03/11] scsi: scsi_debug: Drop scsi_debug_abort() NULL pointer checks
Date: Mon, 13 Mar 2023 08:44:58 +0000 [thread overview]
Message-ID: <20230313084505.1487337-4-john.g.garry@oracle.com> (raw)
In-Reply-To: <20230313084505.1487337-1-john.g.garry@oracle.com>
The SCSI cmnd pointer arg would never be NULL, so drop the check. In
addition, its SCSI device pointer would never be NULL.
The only caller is scsi_send_eh_cmnd() -> scsi_abort_eh_cmnd() ->
scsi_try_to_abort_cmd() -> scsi_try_to_abort_cmd(), and in the origin of
that chain those pointers cannot be NULL.
