Subject: [PATCH 03/11] scsi: scsi_debug: Drop scsi_debug_abort() NULL pointer checks
Date: Tue,  7 Mar 2023 10:55:47 +0000	[thread overview]
Message-ID: <20230307105555.3745277-4-john.g.garry@oracle.com> (raw)
In-Reply-To: <20230307105555.3745277-1-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.
