cpufreq: acpi-cpufreq: Use cpufreq_cpu_get_raw() in ->get()
cpufreq_cpu_get() called by get_cur_freq_on_cpu() is overkill, because the ->get() callback is always invoked in a context in which all of the conditions checked by cpufreq_cpu_get() are guaranteed to be satisfied. Use cpufreq_cpu_get_raw() instead of it and drop the corresponding cpufreq_cpu_put() from get_cur_freq_on_cpu(). Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
