Subject: auxdisplay: ks0108: fix refcount

From: Sudip Mukherjee <[email protected]>

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().
