cpufreq: powernv: Migrate to ->exit() callback instead of ->stop_cpu()
Commit 367dc4aa932b ("cpufreq: Add stop CPU callback to cpufreq_driver interface") added the ->stop_cpu() callback to allow the drivers to do clean up before the CPU is completely down and its state can't be modified. At that time the CPU hotplug framework used to call the cpufreq core's registered notifier for different events like CPU_DOWN_PREPARE and CPU_POST_DEAD. The ->stop_cpu() callback was called during the CPU_DOWN_PREPARE event. This is no longer the case, cpuhp_cpufreq_offline() is called only once by the CPU hotplug core now and we don't really need two separate callbacks for cpufreq drivers, i.e. ->stop_cpu() and ->exit(), as everything can be done from the ->exit() callback itself. Migrate to using the ->exit() callback instead of ->stop_cpu(). Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> [ rjw: Minor changelog edits ] Signed-off-by: Rafael J.
