This is what I thought, too, until I checked the code paths. Who adds entries to that list? Only media_gobj_create() does, and only when type==MEDIA_GRAPH_INTF_DEVNODE. That is called via media_interface_init(), via media_devnode_create(). In the whole kernel, there are two calls to media_devnode_create(): one in dvbdev.c and another one in v4l2-dev.c. Both callers take care for freeing their interface. Both would crash if somebody else would free it for them before they get a chance to do it. Which is the very thing my patch addresses. Did I miss something?
