From b8dc1a35c88dddcf62ce7bc59a7ed4c38c2f7597 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 14 Dec 2012 14:22:10 +0100 Subject: [PATCH] mac80211: further simplify ieee80211_bss_info_change_notify The special case in the function isn't really needed, instead make the suspend code a bit better and also easier to understand and move the warning into the driver op wrapper inline.
