[PATCH v2 0/2] Skip IRQ1 override for two laptops

[PATCH v2 0/2] Skip IRQ1 override for two laptops

[Chuanhong Guo]

The IRQ1 of these two laptops with Ryzen 6000 and Insyde UEFI
are active low, as described in ACPI DSDT. The kernel override
made their keyboard non-functional.
This patchset skips override for them.

Changes since v1:
 Match DMI DMI_PRODUCT_NAME for ThinkBook because the board name
 is used for other completely different Lenovo laptops.
 Add a patch for RedmiBook

[PATCH v2 1/2] ACPI: skip IRQ1 override on Lenovo ThinkBook 14G4+ ARA

[Chuanhong Guo]

The IRQ is described as (Edge, ActiveLow, Shared, ) in ACPI DSDT and
it's correct. The override makes the keyboard interrupt polarity
inverted, resulting in non-functional keyboard.
Add an entry for skipping the override.
