Subject: [PATCH 3.10] cfg80211: check wdev->netdev in connection work
Date: Thu, 23 May 2013 18:12:16 +0200 [thread overview]
Message-ID: <1369325536-20085-1-git-send-email-johannes@sipsolutions.net> (raw)
From: Johannes Berg <johannes.berg@intel.com>
If a P2P-Device is present and another virtual interface triggers
the connection work, the system crash because it tries to check
if the P2P-Device's netdev (which doesn't exist) is up. Skip any
wdevs that have no netdev to fix this.
