There are few races in the frequency invariance support for CPPC driver, namely the driver doesn't stop the kthread_work and irq_work on policy exit during suspend/resume or CPU hotplug.
A proper fix won't be possible for the 5.13-rc, as it requires a lot of changes. Instead of reverting the patch, mark this feature BROKEN for now.
