+Subject: iwlagn: fix command queue timeout
+
+From: Johannes Berg <johannes.berg@intel.com>
+
+commit 282cdb325aea4ebbc42ce753b47cc96145eb54bc upstream.
+
+If the command queue is constantly busy,
+which can happen in P2P, the hangcheck
+timer will frequently find a command in
+it and will eventually reset the device
+because nothing sets the timestamp for
+this queue when commands are processed.
+
+Fix this by setting the timestamp when
+a command completes.
