Since v6.5-rc1 the keyboard on this laptop no longer works. This problem also
existed before v6.0-rc1 commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override
on AMD Zen platforms"), so I suspected the cause to be a9c4a912b7dc ("ACPI:
resource: Remove "Zen" specific match and quirks") which reverted that commit.
Reverting a9c4a912b7dc confirmed this theory.

My specs are:
Laptop model: Lenovo Yoga 7 14ARB7
BIOS: K5CN40WWT66 (latest beta from [1])
CPU: AMD Ryzen 5 6600U
Kernel config: [2]
Distribution: Arch Linux

The issue has been confirmed by at least one other user with this laptop: [3]
