Pull power management and ACPI updates from Rafael Wysocki: "These are fixes on top of the previous PM+ACPI pull requests (including one fix for a 4.1 regression) and two commits adding _CLS-based device enumeration support to the ACPI core and the ATA subsystem that waited for the latest ACPICA changes to be merged. Specifics: - Fix for an ACPI resources management regression introduced during the 4.1 cycle (that unfortunately went into -stable) effectively reverting the bad commit along with the recent fixups on top of it and using an alternative approach to address the underlying issue (Rafael J Wysocki). - Fix for a memory leak and an incorrect return value in an error code path in the ACPI LPSS (Low-Power Subsystem) driver (Rafael J Wysocki). - Fix for a leftover dangling pointer in an error code path in the new wakeup IRQ support code (Rafael J Wysocki). - Fix to prevent infinite loops (due to errors in other places) from happening in the core generic PM domains support code (Geert Uytterhoeven). - Hibernation documentation update/clarification (Uwe Geuder). - Support for _CLS-based device enumeration in the ACPI core and in the ATA subsystem (Suravee Suthikulpanit)" * tag 'pm+acpi-4.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / wakeirq: Avoid setting power.wakeirq too hastily ata: ahci_platform: Add ACPI _CLS matching ACPI / scan: Add support for ACPI _CLS device matching PM / hibernate: clarify resume documentation PM / Domains: Avoid infinite loops in attach/detach code ACPI / LPSS: Fix up acpi_lpss_create_device() ACPI / PNP: Reserve ACPI resources at the fs_initcall_sync stage
