Perry Yuan 4f3085f87b cpufreq: amd-pstate: fix kernel hang issue while amd-pstate unregistering ... In the amd_pstate_adjust_perf(), there is one cpufreq_cpu_get() call to increase increments the kobject reference count of policy and make it as busy. Therefore, a corresponding call to cpufreq_cpu_put() is needed to decrement the kobject reference count back, it will resolve the kernel hang issue when unregistering the amd-pstate driver and register the `amd_pstate_epp` driver instance.
