From 1e9291996c4eedf79883f47ec635235e39d3d6cd Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Tue, 4 Mar 2014 10:28:23 +0200 Subject: iwlwifi: mvm: don't WARN when statistics are handled late 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.
