ACPI: processor_perflib: Simplify code and stop using CPUFREQ_START
acpi_processor_ppc_notifier() can live without using CPUFREQ_START (which is gonna be removed soon), as it is only used while setting ignore_ppc to 0. This can be done with the help of "ignore_ppc < 0" check alone. The notifier function anyway ignores all events except CPUFREQ_ADJUST and dropping CPUFREQ_START wouldn't harm at all. Once CPUFREQ_START event is removed from the cpufreq core, acpi_processor_ppc_notifier() will get called only for CPUFREQ_NOTIFY or CPUFREQ_ADJUST event. Drop the return statement from the first if block to make sure we don't ignore any such events. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
