Commit a9c4a912b7dc ("ACPI: resource: Remove "Zen" specific match and quirks") is causing keyboard problems for quite a log of AMD based laptop users, leading to many bug reports. Revert this change for now, until we can come up with a better fix for the PS/2 IRQ trigger-type/polarity problems on some x86 laptops.
