PVS-Studio warning V649 for Micro-Manager

int AFC::Initialize()
{
  int ret = DEVICE_OK;
  ....
  if (ret != DEVICE_OK)
    return ret;
  AddAllowedValue("DichroicMirrorIn", "0", 0);
  AddAllowedValue("DichroicMirrorIn", "1", 1);
  if (ret != DEVICE_OK)
    return ret;
  ....
}

Not terrible, but second if() does not make sense.


This suspicious code was found in Micro-Manager project by PVS-Studio static code analyzer.
Warning message is:
V649 There are two 'if' statements with identical conditional expressions. The first 'if' statement contains function return. This means that the second 'if' statement is senseless. Check lines: 2918, 2922. LeicaDMI.cpp 2922
