Subject: [PATCH -next 0/3] seq_printf/puts/putc: Start to convert to return void

Many uses of the return value of seq_printf/seq_puts/seq_putc are
incorrect.  Many assume that the return value is the number of
chars emitted into a buffer like printf/puts/putc.

It would be better to make the return value of these functions void
to avoid these misuses.

Start to do so.
Convert seq_overflow to a public function from a static function.

Remove the return uses of seq_printf/seq_puts/seq_putc from net.
Add a seq_overflow function call instead.

Joe Perches (3):
  seq: Add a seq_overflow test.
  batman-adv: Use seq_overflow
  netfilter: Use seq_overflow
