Subject: [PATCH 07/11] scsi: scsi_debug: Drop scsi_debug_host_reset() device NULL pointer check
Date: Tue, 7 Mar 2023 10:55:51 +0000 [thread overview]
Message-ID: <20230307105555.3745277-8-john.g.garry@oracle.com> (raw)
In-Reply-To: <20230307105555.3745277-1-john.g.garry@oracle.com>
The check for device pointer for the SCSI command is unnecessary, so drop
it.
The only caller is scsi_try_host_reset() -> eh_host_reset_handler(),
and there that pointer cannot be NULL.
Indeed, there is already code later in the same function which does not
check the device pointer for the SCSI command.
