src/sys/dev/trm/trm.c:2484] -> [src/sys/dev/trm/trm.c:2486]: (warning)
Identical inner 'if' condition is always true.

Source code is

 if ((((ptr->Vers & 0x07) >=3D 2) ||
                                              ((ptr->RDF & 0x0F) =3D=3D 2))=
 &&
                                            (ptr->Flags & SCSI_INQ_CMDQUEUE=

                                            (pDCB->DevMode & TAG_QUEUING_) =

                                            (pDCB->DevMode & EN_DISCONNECT_=

                                                if (pDCB->DevMode &
                                                    TAG_QUEUING_) {
                                                        pDCB->

                                                } else {

Duplicate in the TAG_QUEUING. Else clause can never run.
