Merge tag 'pm-4.10-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki: "These add a quirk to intel_pstate to work around a firmware setting that leads to frequency scaling issues (discovered recently) on some Intel Kaby Lake processors, fix up the recently added brcmstb-avs cpufreq driver and avoid false-positive warnings from the runtime PM framework triggered by recent changes in i915. Specifics: - Add an intel_pstate driver quirk to work around a firmware setting that leads to frequency scaling issues on desktop Intel Kaby Lake processors in some configurations if the hardware-managed P-states (HWP) feature is in use (Srinivas Pandruvada) - Fix up the recently added brcmstb-avs cpufreq driver: fix a bug related to system suspend and change the sysfs interface to match the user space expectations (Markus Mayer) - Modify the runtime PM framework to avoid false-positive warnings from the might_sleep_if() assertions in it (Rafael Wysocki)" * tag 'pm-4.10-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / runtime: Avoid false-positive warnings from might_sleep_if() cpufreq: intel_pstate: Disable energy efficiency optimization cpufreq: brcmstb-avs-cpufreq: properly retrieve P-state upon suspend cpufreq: brcmstb-avs-cpufreq: extend sysfs entry brcm_avs_pmap
