2 Subject: ctcm: avoid crash in ctcm_remove_device
3 References: bnc#487755,LTC#52679
5 Symptom: crash in debugging call of ctcm_remove_device
6 Problem: Channels are already removed when setting a
7 ctcm-device offline. Thus ctcm_remove_device must
8 not refer to channel information.
9 Solution: delete channel information from the trace call in
