Subject: net: sctp: attribute printl with __printf for gcc fmt checks
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=be3e45810bb1ee0bdfa93f6b9532d8c451e50f48;p=~shefty%2Frdma-dev.git

net: sctp: attribute printl with __printf for gcc fmt checks

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]
