PVS-Studio warning V501 for ReactOS

ir_visitor_status
ir_validate::visit_leave(ir_loop *ir)
{
  if (ir->counter != NULL) {
    if ((ir->from == NULL) || (ir->from == NULL) ||
        (ir->increment == NULL)) {
  ....
}

This is what should have been written here: (ir->from == NULL) || (ir->to == NULL)


This suspicious code was found in ReactOS project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions to the left and to the right of the '||' operator: (ir->from == 0) || (ir->from == 0) ir_validate.cpp 123
