Subject: [PATCH v2 0/4] of/irq: Misc msi-parent handling fixes/clean-ups

This is a follow up to [1] - with additional patches that are addressing
Rob's feedback (pcie-layerscape-gen4 was removed from the kernel, Yay !)
and other bits and bobs I noticed while staring at the code.

Patch (1) is a fix and technically we would like to get it in v6.18 please.

Patch (3) is compile-tested only, I can not run it on HW, I do not have it,
Scott, Ray please test it if you can.
