Adding some more stuff to the confusion: Currently I think it is correct 
that hid-sensor-hub still receives the event, even after 
rtc-hid-sensor-time called hid_device_io_stop() and probe() failed. The 
reason the same reason, why hid-sensor-hub uses mfd, the actual hardware 
device might be shared by different drivers (therfor -hub).
