From: Johannes Berg Date: Thu, 10 Jan 2013 22:55:33 +0000 (+0100) Subject: mac80211: fix resume from WoWLAN X-Git-Tag: v3.9-rc2~24^2~15^2^2~24^2~134 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d888130a024d1d1e8b2c3d0c9841a218fc0aed9e;p=platform%2Fkernel%2Flinux-stable.git mac80211: fix resume from WoWLAN My commit 529ba6e9313dbe60dab7e72c6fdf647a012e9f5b ("mac80211: clean up association better in suspend") introduced a bug when resuming from WoWLAN when a device reset is desired. This case must not use the suspend_bss_conf as it hasn't been stored.
