I've now also verified if hid-sensor-hub receives an event with
sensor_hub_raw_event() in the error-path (hid_device_io_stop() called
and probe() failed), and this still *does* happen. That event (input
report) doesn't come through hid-sensor-hub to my driver, but I think
this is because of my call to sensor_hub_remove_callback() which is in
the error path too.
So I actually wonder why the input report still is reported from the
hid-subsystem to hid-sensor-hub, even after I've called
hid_device_io_stop() and probe() failed.
Maybe everything is still ok and I just got confused with the somehow
complicate interactions between the usb- and hid-subsystem,
hid-sensor-hub (which uses MFD) and rtc-hid-sensor-time.

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).
