2017-02-06Input: xpad - fix stuck mode button on Xbox One S padCameron Gutman1-0/+33
The Xbox One S requires an ack to its mode button report, otherwise it continuously retransmits the report. This makes the mode button appear to be stuck down after it is pressed for the first time. Signed-off-by: Cameron Gutman <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2017-02-01Input: refuse to register absolute devices without absinfoDmitry Torokhov1-0/+6
If device is supposed to send absolute events (i.e. EV_ABS bit is set in dev->evbit) but dev->absinfo is not allocated, then the driver has done something wrong, and we should not register such device. Otherwise we'll crash later, when driver tries to send absolute event.
