Merge tag 'acpi-6.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes from Rafael Wysocki:
"These fix an ACPI PRM (Platform Runtime Mechanism) issue and add two
new DMI quirks, one for an ACPI IRQ override and one for lid switch
detection:
- Make acpi_parse_prmt() look for EFI_MEMORY_RUNTIME memory regions
only to comply with the UEFI specification and make PRM use
efi_guid_t instead of guid_t to avoid a compiler warning triggered
by that change (Koba Ko, Dan Carpenter)
- Add an ACPI IRQ override quirk for LG 16T90SP (Christian Heusel)
- Add a lid switch detection quirk for Samsung Galaxy Book2 (Shubham
Panwar)"
