Subject: [PATCH v4] ACPI: skip IRQ1 override on 3 laptops
Date:   Thu, 30 Jun 2022 09:31:23 +0800

The IRQ1 of these laptops with Ryzen 6000 and Insyde UEFI are active
low and defined in legacy format in ACPI DSDT. The kernel override
makes the keyboard interrupt polarity inverted, resulting in
non-functional keyboard.

Skip legacy IRQ override for:
Lenovo ThinkBook 14G4+ ARA
Redmi Book Pro 15 2022
Asus Zenbook S 13 OLED UM5302
