Merge tag 'acpi-6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix the ACPI initialization ordering on ARM and ACPI IRQ
management in the cases when irq_create_fwspec_mapping() fails.
Specifics:
- Fix ACPI initialization ordering on ARM that was changed
incorrectly during the 6.5 development cycle (Hanjun Guo)
- Make acpi_register_gsi() return an error code as appropriate when
irq_create_fwspec_mapping() returns 0 on failure (Sunil V L)"

ACPI: bus: Move acpi_arm_init() to the place of after acpi_ghes_init()
ACPI: irq: Fix incorrect return value in acpi_register_gsi()
