Commit Message

  commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on
AMD Zen platforms") attempted to overhaul the override logic so it
didn't apply on X86 AMD Zen systems.  This was intentional so that
systems would prefer DSDT values instead of default MADT value for
IRQ 1 on Ryzen 6000 systems which use ActiveLow for IRQ1.

This turned out to be a bad assumption because several vendors seem
to add Interrupt Source Override but don't fix the DSDT. A pile of
quirks was collecting that proved this wasn't sustaintable.

Adjust the logic so that only IRQ1 is overridden in Ryzen 6000 case.

This effectively reverts the following commits:
commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang
GMxRGxx")
commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7")
commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad")
commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15")

Tested on Lenovo Thinkbook 14G4+ ARA with Ryzen 7 6800H.
The keyboard still works with this patch applied.

Thanks!
Could you reply directly to the v3 patch instead?

Then b4 am will be able to pick up your tag directly.
