From: Joe Perches <joe@...ches.com>
To: Pablo Neira Ayuso <pablo@...filter.org>
Cc: netfilter-devel <netfilter-devel@...r.kernel.org>,

Subject: [PATCH net-next] netfilter: Remove uses of return value of
seq_printf/puts/putc
These functions are soon going to return void so remove the
return value uses.
Convert the return value to test seq_has_overflowed() instead.
