Merge tag 'pm-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki: "This includes a stable-candidate cpufreq-dt driver problem fix and annotations of tracepoints in the runtime PM framework. Specifics: - Fix the definition of the cpufreq-dt driver's machines table introduced during the 4.7 cycle that should be NULL-terminated, but the termination entry is missing from it (Wei Yongjun). - Annotate tracepoints in the runtime PM framework's core so as to allow the functions containing them to be called from the idle code path without causing RCU to complain about illegal usage (Paul McKenney)" * tag 'pm-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / runtime: Add _rcuidle suffix to allow rpm_idle() use from idle PM / runtime: Add _rcuidle suffix to allow rpm_resume() to be called from idle cpufreq: dt: Add terminate entry for of_device_id tables
