The thing is to avoid doing harm to the kernel if a single driver can't work as expected, especially when we have an user input (the firmware). The firmware being a valid one is another topic. But honestly I'm not sure if a wrong returned value would change anything here, apart from not probing the driver successfully as we know something went wrong.
