I don't think it's likely anybody will need it before .probe() completes, because the purpose of drvdata is for an external driver entry point to locate its device data, and none of those entry points will be called until after .probe() completes successfully. But I don't care at all if we do it earlier, as long as all the drivers do it the same way.
