From: "Steven Rostedt (Red Hat)" [ REQUEST FOR ACKS ] The seq_printf() and friends are having their return values removed. The print_conntrack() returns the result of seq_printf(), which is meaningless when seq_printf() returns void. Might as well remove the return values of print_conntrack() as well.
