* o dissect_scsi_cdb - invoked on receiving a SCSI Command
* void dissect_scsi_cdb (tvbuff_t *, packet_info *, proto_tree *, guint,
- * guint);
+ * guint);
* o dissect_scsi_payload - invoked to decode SCSI responses
* void dissect_scsi_payload (tvbuff_t *, packet_info *, proto_tree *, guint,
* gboolean, guint32);
* SCSI command set (SPC-2/3) is decoded for all SCSI devices. If there is a
* mixture of devices in the trace, some with Inquiry response and some
* without, the user preference is used only for those devices whose type the
- * decoder has not been able to determine.
