[PATCH 01/14] cpufreq: intel_pstate: Update pid_params.sample_rate_ns in pid_param_set()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wyso...@intel.com>

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)
