I missed this in the first round, but tripped over it when looking at one of the follow up patches.
How is that supposed to work?
1) intel_cqm_event_destroy() is still in the code and unused which emits a compiler warning, but that can obviously be ignored for a good measure.
2) How would any testing of this mess actually work?
Not all all. Nothing ever tears down an event. So you just leave everything hanging around probably with dangling pointers left and right.
So now the 'Tests: Same as before.' in the so called changelog makes sense:
'Same as before' means: Completely untested and broken.
Thanks,
