From 8c1dddd6070a900918561f162621ef4957ff36c2 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sun, 30 Sep 2012 17:12:45 +0200 Subject: [PATCH] mac80211: use __printf attribute in debugfs The internal function mac80211_format_buffer() has a printf-style argument list, so add the attribute to have gcc verify that list.
