Merge tag 'pm-5.2-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki: "These fix three issues in the system-wide suspend and hibernation area related to PCI device PM handling by suspend-to-idle, device wakeup optimizations and arbitrary differences between suspend and hiberantion. Specifics: - Modify the PCI bus type's PM code to avoid putting devices left by their drivers in D0 on purpose during suspend to idle into low-power states as doing that may confuse the system resume callbacks of the drivers in question (Rafael Wysocki). - Avoid checking ACPI wakeup configuration during system-wide suspend for suspended devices that do not use ACPI-based wakeup to allow them to stay in suspend more often (Rafael Wysocki). - The last phase of hibernation is analogous to system-wide suspend also because on platforms with ACPI it passes control to the platform firmware to complete the transision, so make it indicate that by calling pm_set_suspend_via_firmware() to allow the drivers that care about this to do the right thing (Rafael Wysocki)" * tag 'pm-5.2-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PCI: PM: Avoid possible suspend-to-idle issue ACPI: PM: Call pm_set_suspend_via_firmware() during hibernation ACPI/PCI: PM: Add missing wakeup.flags.valid checks
