Since delayed work is used here, use of flush_scheduled_work() is not sufficient in atkbd_disconnect(). It does not wait for scheduled delayed work to finish. This patch prevents delayed work to be processed after freeing atkbd structure (used struct delayed_work is part of atkbd) by cancelling this delayed work.
