[REGRESSION] IRQ override revert breaks keyboard on Lenovo Yoga 7 14ARB7

[August Wikerfors]

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

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]

This is unfortunate.  Before we go adding more quirks for your system, 
can you please check for a BIOS upgrade for your system?  If it's 
happening with the latest BIOS, then can you please open a kernel 
bugzilla with an acpidump and dmidecode included?

The latest released BIOS is K5CN40WW, I'm using K5CN40WWT66 which is a 
later beta that partially mitigates a Windows BSOD issue. I've opened a 
Bugzilla report with the dmidecode here: 
https://bugzilla.kernel.org/show_bug.cgi?id=217718

For the acpidump I'm not sure what parts could be sensitive so I will 
e-mail it directly to you.
