HID: add autodetection of multitouch devices
As mentioned by http://www.microsoft.com/whdc/device/input/DigitizerDrvs_touch.mspx multitouch devices are those that have the input report HID_CONTACTID. This patch detects this and unloads the generic-usb driver. Signed-off-by: Benjamin Tissoires <benjamin.tissoires@enac.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
