They were protected with port->tty_sem at the same time. By that commit, the counting was switched to tty_port's one, but the locking remained the old one. So the count was not protected by any lock anymore. The driver should not test whether it raced with HUP or not anyways. With the new refcounted tty model, it just should proceed as nothing happened because all needed info is still there. In respect to this, let's drop the useless and unprotected tests (tty_port->count is protected by tty_port->lock).
