Hi Hoan,
Apologies for the last reply.

I don't believe this look is necessary. AFAICT, acpi_match_device_ids()
already iterates over the id table it is given.

As above, and as I covered in my reply to v1, I think the above should
be:
acpi_id = acpi_match_device_ids(adev, xgene_pmu_acpi_type_match);
if (!acpi_id)
return AE_OK;
... or am I missing something?
With that change:
