Merge tag 'acpi-7.1-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI support fixes from Rafael Wysocki: "These fix two potential refcount leaks in error code paths in the ACPI core code, address a recently introduced build breakage related to the CPU UID handling consolidation, fix up a recently added MAINTAINERS entry, fix the quirk list in the ACPI video bus driver, and add a new quirk to it: - Add an acpi_get_cpu_uid() stub helper to address an x86 Xen support build breakage (Arnd Bergmann) - Use acpi_dev_put() in object add error paths in the ACPI core to avoid refcount leaks (Guangshuo Li) - Adjust the file entry in the recently added NVIDIA GHES HANDLER entry in MAINTAINERS to the actual existing file (Lukas Bulwahn) - Add backlight=native quirk for Dell OptiPlex 7770 AIO to the ACPI video bus driver (Jan Schär) - Move Lenovo Legion S7 15ACH6 quirk to the right section of the quirk list in the ACPI video bus driver (Hans de Goede)" * tag 'acpi-7.1-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: video: Move Lenovo Legion S7 15ACH6 quirk to the right section ACPI: video: Add backlight=native quirk for Dell OptiPlex 7770 AIO ACPI: add acpi_get_cpu_uid() stub helper MAINTAINERS: adjust file entry in NVIDIA GHES HANDLER ACPI: scan: Use acpi_dev_put() in object add error paths
