Yeah agreed. It's almost certainly some code that needs to change from this:

  testResult = TestFingerprint(fingerprint);
  if(testResult)
    return UNLOCK_OK;
  else
    return UNLOCK_FAIL;

to this:

  testResult = TestFingerprint(fingerprint);
  if(testResult == RESULT_OK)
    return UNLOCK_OK;
  else
    return UNLOCK_FAIL;
