From 61b0f5d7c41408ff523a5cd3925feafa82b971f5 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 4 Aug 2016 08:57:59 +0200 Subject: [PATCH] iwlwifi: mvm: compare full command ID When comparing command IDs, the group should be taken into account so the same command/notification from a different group doesn't trigger anything unexpected. Fix this by comparing to the wide ID.
