The last patch was careful to maintain backwards-compatible behavior
by forcing device_type to BTN_TOOL_PEN (and printing a warning) if it
were still uninitialized after scanning the HID descriptor and applying
quirks. We should be more strict with HID_GENERIC devices, however,
since there is no a priori guarantee that it is a tablet or touchpad.
If the device_type is still uninitialized for a HID_GENERIC device then
we assume that it isn't something the driver can work with and so fail
the probe.
