From 1a106de6e6543e7d44dbe1bc5f37a8964607dfa6 Mon Sep 17 00:00:00 2001 From: "David S. Miller" <davem@davemloft.net> Date: Sun, 1 Apr 2012 20:22:22 -0400 Subject: [PATCH] enic: Stop using NLA_PUT*(). These macros contain a hidden goto, and are thus extremely error prone and make code hard to audit. Signed-off-by: David S.
