Pull ACPI fixes from Rafael Wysocki: "These are new ACPI IRQ override quirks, low-power S0 idle (S0ix) support adjustments and ACPI backlight handling fixes, mostly for platforms using AMD chips. Specifics: - Add ACPI IRQ override quirks for Asus ExpertBook B2502, Lenovo 14ALC7, and XMG Core 15 (Hans de Goede, Adrian Freund, Erik Schumacher). - Adjust ACPI video detection fallback path to prevent non-operational ACPI backlight devices from being created on systems where the native driver does not detect a suitable panel (Mario Limonciello). - Fix Apple GMUX backlight detection (Hans de Goede). - Add a low-power S0 idle (S0ix) handling quirk for HP Elitebook 865 and stop using AMD-specific low-power S0 idle code path for systems with Rembrandt chips and newer (Mario Limonciello)" * tag 'acpi-6.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: x86: s2idle: Stop using AMD specific codepath for Rembrandt+ ACPI: x86: s2idle: Force AMD GUID/_REV 2 on HP Elitebook 865 ACPI: video: Fix Apple GMUX backlight detection ACPI: resource: Add Asus ExpertBook B2502 to Asus quirks ACPI: resource: do IRQ override on Lenovo 14ALC7 ACPI: resource: do IRQ override on XMG Core 15 ACPI: video: Don't enable fallback path for creating ACPI backlight by default drm/amd/display: Report to ACPI video if no panels were found ACPI: video: Allow GPU drivers to report no panels
