From 693560d364dc64efed3da660b62948368132754a Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Thu, 7 Jul 2011 23:33:39 +0530 Subject: [PATCH] mac80211: Restart STA timers only on associated state [ upstream commit 676b58c27475a9defccc025fea1cbd2b141ee539 ] A panic was observed when the device is failed to resume properly, and there are no running interfaces. ieee80211_reconfig tries to restart STA timers on unassociated state.
