From: Roderick Colenbrander <[email protected]>

commit a687c5765b5ae19fe559e14615ddc87ebb46d409 upstream.

When a user connects a DS4 twice using USB and BT, we reject the second device connection after the setup work. We then perform a cleanup, but during cleanup we are not removing the touchpad device. This leads to leakage of an input device, which we would never remove. It can likely result into a kernel oops as well when the touchpad evdev node is accessed and the underlaying HID device has been removed from the system.
