As the class is vendor-specific, we have to still match against vendor id as well, though.

In xpad_probe() it gets changed to either MAP_DPAD_TO_BUTTONS or MAP_DPAD_TO_AXES, depending on the module parameter dpad_to_buttons. However, MAP_DPAD_UNKNOWN is defined as -1, while the field is u8. This results in actual value of 255, causing the MAP_DPAD_UNKNOWN check in xpad_probe() to fail. Fix that by defining MAP_DPAD_UNKNOWN as 2 instead. Also, setting module parameter dpad_to_buttons to 1 should obviously map dpad to buttons, while the default behaviour (0) should be to map dpad to axes. However, dpad_to_buttons is directly assigned to xpad->dpad_mapping, and as MAP_DPAD_TO_BUTTONS is 0, the actual behaviour is reversed. Fix that by negating dpad_to_buttons in assignment.
