Since cpufreq_update_limits() obtains a cpufreq policy pointer for the given CPU and reference counts the corresponding policy object, it may as well pass the policy pointer to the cpufreq driver's ->update_limits() callback which allows that callback to avoid invoking cpufreq_cpu_get() for the same CPU. Accordingly, redefine ->update_limits() to take a policy pointer instead of a CPU number and update both drivers implementing it, intel_pstate and amd-pstate, as needed. Signed-off-by: Rafael J.
