Merge tag 'acpi-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "These update the ACPICA code in the kernel to upstream revision 20200430, fix several reference counting errors related to ACPI tables, add _Exx / _Lxx support to the GED driver, add a new acpi_evaluate_reg() helper, add new DPTF battery participant driver and extend the DPFT power participant driver, improve the handling of memory failures in the APEI code, add a blacklist entry to the backlight driver, update the PMIC driver and the processor idle driver, fix two kobject reference count leaks, and make a few janitory changes. Specifics: - Update the ACPICA code in the kernel to upstream revision 20200430: - Move acpi_gbl_next_cmd_num definition (Erik Kaneda). - Ignore AE_ALREADY_EXISTS status in the disassembler when parsing create operators (Erik Kaneda). - Add status checks to the dispatcher (Erik Kaneda). - Fix required parameters for _NIG and _NIH (Erik Kaneda). - Make acpi_protocol_lengths static (Yue Haibing). - Fix ACPI table reference counting errors in several places, mostly in error code paths (Hanjun Guo). - Extend the Generic Event Device (GED) driver to support _Exx and _Lxx handler methods (Ard Biesheuvel). - Add new acpi_evaluate_reg() helper and modify the ACPI PCI hotplug code to use it (Hans de Goede). - Add new DPTF battery participant driver and make the DPFT power participant driver create more sysfs device attributes (Srinivas Pandruvada). - Improve the handling of memory failures in APEI (James Morse). - Add new blacklist entry for Acer TravelMate 5735Z to the backlight driver (Paul Menzel). - Add i2c address for thermal control to the PMIC driver (Mauro Carvalho Chehab). - Allow the ACPI processor idle driver to work on platforms with only one ACPI C-state present (Zhang Rui). - Fix kobject reference count leaks in error code paths in two places (Qiushi Wu). - Delete unused proc filename macros and make some symbols static (Pascal Terjan, Zheng Zengkai, Zou Wei)" * tag 'acpi-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (32 commits) ACPI: CPPC: Fix reference count leak in acpi_cppc_processor_probe() ACPI: sysfs: Fix reference count leak in acpi_sysfs_add_hotplug_profile() ACPI: GED: use correct trigger type field in _Exx / _Lxx handling ACPI: DPTF: Add battery participant driver ACPI: DPTF: Additional sysfs attributes for power participant driver ACPI: video: Use native backlight on Acer TravelMate 5735Z arm64: acpi: Make apei_claim_sea() synchronise with APEI's irq work ACPI: APEI: Kick the memory_failure() queue for synchronous errors mm/memory-failure: Add memory_failure_queue_kick() ACPI / PMIC: Add i2c address for thermal control ACPI: GED: add support for _Exx / _Lxx handler methods ACPI: Delete unused proc filename macros ACPI: hotplug: PCI: Use the new acpi_evaluate_reg() helper ACPI: utils: Add acpi_evaluate_reg() helper ACPI: debug: Make two functions static ACPI: sleep: Put the FACS table after using it ACPI: scan: Put SPCR and STAO table after using it ACPI: EC: Put the ACPI table after using it ACPI: APEI: Put the HEST table for error path ACPI: APEI: Put the error record serialization table for error path ...
