From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit 1e9291996c4eedf79883f47ec635235e39d3d6cd upstream. Since the statistics handler is asynchrous, it can very well be that we will handle the statistics (hence the RSSI fluctuation) when we already disassociated. Don't WARN on this case.
