CVE-2026-98502

In the Linux kernel, the following vulnerability has been resolved:

HID: alps: unregister DualPoint Stick input device on remove

alps_input_configured() allocates a second input device ("DualPoint
Stick") with input_allocate_device() and registers it, but the
alps_driver struct has no .remove handler and input2 is not tracked in
hdev->inputs.  The default remove path (hid_hw_stop -> hidinput_disconnect)
only iterates hdev->inputs, so input2 is never unregistered and leaks
on every device removal.

Add a .remove handler that stops the device first (preventing URB
callbacks from touching input2 during teardown) and then unregisters
input2.
