cpufreq: intel_pstate: Use locking in intel_cpufreq_verify_policy() Race conditions are possible if intel_cpufreq_verify_policy() is executed in parallel with global limits updates from sysfs, so the invocation of intel_pstate_update_perf_limits() in it should be carried out under intel_pstate_limits_lock. Make that happen. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
