I guess this should be fine:
f3b0cbce01 has no more impact (there is no USB_DEVICE_ID_MS_*_2
anymore)

e24d0d399b2f will properly add the HID_GROUP_SENSOR_HUB to the sensors
if the report descriptor is properly set.

Given that the group SENSOR_HUB will be set, no other hid driver will
pick them, so this patch just adds the HID_SENSOR_HUB_ENUM_QUIRK to the
actual sensors in the surface 2.

So:
