cpufreq: intel_pstate: Update pid_params.sample_rate_ns in pid_param_set()
Fix the debugfs interface for PID tuning to actually update pid_params.sample_rate_ns on PID parameters updates, as changing pid_params.sample_rate_ms via debugfs has no effect now. Fixes: a4675fbc4a7a (cpufreq: intel_pstate: Replace timers with utilization update callbacks) Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
