Subject: [PATCH] auxdisplay: ks0108: fix refcount

commit bab383de3b84e584b0f09227151020b2a43dc34c upstream.

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().
