The CTI module has some hard coded refcounting code that has a leak. For example running perf and then trying to unload it fails: perf record -e cs_etm// -a -- ls rmmod coresight_cti rmmod: ERROR: Module coresight_cti is in use The coresight core already handles references of devices in use, so by making CTI a normal helper device, we get working refcounting for free.
