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)"
