Subject: irq: Invalid fwnode type (2) for irqdomain

Dear Linux folks,

On a Lenovo X60t with coreboot based firmware testing the latest master
branch from Linus, the message below is new, and isn’t there with Linux
4.12.

```
irq: Invalid fwnode type (2) for irqdomain
```

`git blame kernel/irq/irqdomain.c` shows, the message is added in
commit d59f661 (genirq: Allow fwnode to carry name information only).

The commit message describes the warning.

> Warn if an invalid node is supplied and treat it like no node. This
> happens e.g. with i2 devices on x86 which hand in an ACPI type node
> which has no interface for retrieving the name.

How can I find out, how the ACPI/ASL has to be fixed?

Kind regards,

Paul
