From a6cc5163149532734b84c86cbffa4994e527074b Mon Sep 17 00:00:00 2001 From: Matti Gottlieb Date: Mon, 29 Sep 2014 11:46:04 +0300 Subject: iwlwifi: mvm: ROC - bug fixes around time events and locking Don't add the time event to the list. We added it several times the same time event, which leads to an infinite loop when walking the list. Since we (currently) don't support more than one ROC for STA vif at a time, enforce this and don't add the time event to any list. We were also missing the locking of the mutex which led to a lockdep splat - fix that.
