Hi,
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.
#regzbot introduced: a9c4a912b7dc

Laptop model: Lenovo Yoga 7 14ARB7

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