Input: joydev - blacklist ds3/ds4/udraw motion sensors
Introduce a device table used for blacklisting devices. We currently blacklist the motion sensor subdevice of THQ Udraw and Sony ds3/ds4. Signed-off-by: Roderick Colenbrander <roderick.colenbrander@sony.com> [dtor: siwtched to blacklist built on input_device_id and using input_match_device_id()] Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
