Pull power management fixes from Rafael Wysocki: "These add a check to avoid recent suspend-to-idle power regression on systems with NVMe drives where the PCIe ASPM policy is "performance" (or when the kernel is built without ASPM support), fix an issue related to frequency limits in the schedutil cpufreq governor and fix a mistake related to the PM QoS usage in the cpufreq core introduced recently. Specifics: - Disable NVMe power optimization related to suspend-to-idle added recently on systems where PCIe ASPM is not able to put PCIe links into low-power states to prevent excess power from being drawn by the system while suspended (Rafael Wysocki). - Make the schedutil governor handle frequency limits changes properly in all cases (Viresh Kumar). - Prevent the cpufreq core from treating positive values returned by dev_pm_qos_update_request() as errors (Viresh Kumar)" * tag 'pm-5.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: nvme-pci: Allow PCI bus-level PM to be used if ASPM is disabled PCI/ASPM: Add pcie_aspm_enabled() cpufreq: schedutil: Don't skip freq update when limits change cpufreq: dev_pm_qos_update_request() can return 1 on success
