The default remove path (hid_hw_stop -> hidinput_disconnect)\nonly iterates hdev->inputs, so input2 is never unregistered and leaks\non every device removal.\n\nAdd a .remove handler that stops the device first (preventing URB\ncallbacks from touching input2 during teardown) and then unregisters\ninput2."
