  * scsi_add_lun - allocate and fully initialze a scsi_device
- * @sdevscan:	holds information to be stored in the new scsi_device
- * @sdevnew:	store the address of the newly allocated scsi_device
+ * @sdev:	holds information to be stored in the new scsi_device
  * @inq_result:	holds the result of a previous INQUIRY to the LUN
  * @bflags:	black/white list flag
+ * @async:	1 if this device is being scanned asynchronously
  *
  * Description:
- *     Allocate and initialize a scsi_device matching sdevscan. Optionally
- *     set fields based on values in *@bflags. If @sdevnew is not
- *     NULL, store the address of the new scsi_device in *@sdevnew (needed
- *     when scanning a particular LUN).
+ *     Initialize the scsi_device @sdev.  Optionally set fields based
+ *     on values in *@bflags.
  *
  * Return:
  *     SCSI_SCAN_NO_RESPONSE: could not allocate or setup a scsi_device
