Not my area of expertise (so take this with a gain of salt), but I'm
aware of something that afaics concerns this:
A few days ago a patch was merged to mainline that afaics hopefully
might make a change like your unnecessary. See a9c4a912b7d ("ACPI:
resource: Remove "Zen" specific match and quirks") in mainline or here:
https://lore.kernel.org/all/20230601221151.670-1-mario.limonciello@amd.com/
Might be worth giving a try.
There is a rough plan to backport this to stable kernels, unless
problems show up.
Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
