From 729a7ba172bcc0dc014dc7c49d672377ae6cde54 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 1 Aug 2012 20:54:52 +0200 Subject: [PATCH] mac80211: clear timer bits when disconnecting There's a corner case that can happen when we suspend with a timer running, then resume and disconnect. If we connect again, suspend and resume we might start timers that shouldn't be running. Reset the timer flags to avoid this. This affects both mesh and managed modes.
