While fixing various gcc -Wshadow warnings I came across something which 
seems incorrect in packet-camel-template.c in dissect-camel_arg()
(and in dissect_camel_res()).

Specifically: the local variable 'opcode' seems to be set but is never used.

There is a global variable 'opcode' so I'm suspecting that the local 
declaration shouldn't be there.

Can someone who is familiar with the code confirm this ?

Thanks

Bill

*tree _U_) {
  int offset;
  rose_ctx_t *rctx;
  gint32 opcode;
  /*

  offset = 0;
  rctx = get_rose_ctx(pinfo->private_data);
  DISSECTOR_ASSERT(rctx);
  if (rctx->d.pdu != 1)  /* invoke */
    return offset;
  if (rctx->d.code != 0)  /* local */
    return offset;
  opcode = rctx->d.code_local;

  return offset;
}
