auxdisplay: ks0108: fix refcount
parport_find_base() will implicitly do parport_get_port() which increases the refcount. Then parport_register_device() will again increment the refcount. But while unloading the module we are only doing parport_unregister_device() decrementing the refcount only once. We add an parport_put_port() to neutralize the effect of parport_get_port().
