Avoid Coverity BAD_COMPARE, but honestly I don't get it at all...

int readCOTAGUid(void) {
>>>     CID 337768:  Incorrect expression  (BAD_COMPARE)
>>>     This implicit conversion to a function pointer is suspicious: "CmdCOTAGRead > NULL".
130         return CmdCOTAGRead > 0;

This is just an int compared to zero, why it thinks it's a null pointer??
