+From: Gerald Schaefer <geraldsc@de.ibm.com>
+Subject: ctcm: avoid crash in ctcm_remove_device
+References: bnc#487755,LTC#52679
+
+Symptom:     crash in debugging call of ctcm_remove_device
+Problem:     Channels are already removed when setting a
+             ctcm-device offline. Thus ctcm_remove_device must
+             not refer to channel information.
+Solution:    delete channel information from the trace call in
+             ctcm_remove_device.
+
