From c815797663b72e3ac1736f1886538152bc48e4af Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 23 May 2013 18:10:21 +0200 Subject: cfg80211: check wdev->netdev in connection work 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.
