Ignore NULL pool in testSetVolumeType to silence Coverity, even though we only call it with NULL pool when vol is also NULL. (13) Event var_deref_model: Passing null pointer "inputpool" to function "testSetVolumeType(virStorageVolDefPtr, virStoragePoolDefPtr)", which dereferences it. [details] Also see events: [assign_zero] 95 testSetVolumeType(inputvol, inputpool);
