Add a .remove handler that stops the device first, preventing URB callbacks from touching input2 during teardown, and then unregisters the second DualPoint Stick input device (input2).
Linux kernel HID alps driver .remove handler = stop the device, then unregister input2
Event History
Frequently Asked Questions
What systems are exposed to this issue?
Systems using the Linux kernel with the ALPS HID driver and a DualPoint device that causes the driver to allocate its secondary "DualPoint Stick" input device are exposed. The leak occurs when that device is removed.
Does removal or disconnection trigger the problem?
Yes. Each device removal can leave the secondary input device registered because the default HID removal path does not track or unregister it.
What is the impact if the device is repeatedly removed and reconnected?
The secondary input device leaks on every removal. The fix adds driver-specific teardown that stops the device before unregistering the secondary input device, preventing URB callbacks from accessing it during teardown.
