Subject: [PATCH] net: sctp: attribute printl with __printf for gcc fmt checks
Date: Wed,  1 May 2013 14:59:23 +0200	[thread overview]
Message-ID: <1367413163-2817-1-git-send-email-dborkman@redhat.com> (raw)

Let GCC check for format string errors in sctp's probe printl
function. This patch fixes the warning when compiled with W=1:

net/sctp/probe.c:73:2: warning: function might be possible candidate
for 'gnu_printf' format attribute [-Wmissing-format-attribute]
