And yet you do:

+	err = acpi_parse_aspt(&res[0], &pdata);
+	if (err)
+		return err;

You don't trust the ACPI stack, and yet you're parsing an ACPI table?!?!
You have to make up your mind here.

Btw, you still haven't answered my question about doing:

	devm_request_irq(dev, 9, ..)

where 9 is the default ACPI interrupt.

You can have some silly table tell you what to map or you can simply map
IRQ 9 and be done with it. In this second case you can *really* not
trust ACPI because you know which IRQ it is.
