You really should register the notifier _AFTER_ registering the pmu. That

Correct, Will fix the notifier leak

It's not only a notifier leak. The existing code also leaks memory. Please fix
that before adding the new stuff in a seperate patch.

ok..Makes sense. will send the notifier and memory leak fix in seperate patch as its a existing cqm issue.

I had added a kfree(str) in the end for the memory leak fix in the current patch.

if (ret) {
mbm_enabled = false;
cqm_enabled = false;
