One more missed example,

Two variants of the IRQ resources in the table for the _same_ device
but on different platforms.

--Variant1--
Device(XYZ)
_CRS1() {
 Interrupt()
 GpioInt()
 Interrupt()
}

--Variant2--
Device(XYZ)
_CRS2() {
 GpioInt()
 Interrupt()
 Interrupt()
}

How to always get second resource?
