Sure. Adding in the info that Jonas provided about what commit
specifically broke me would also be nice. I'll try to send out a new
CL with improved wording tomorrow.

That sounds like a great idea. ...but not something I'm going to do.
I'm not personally on a mission to track down everyone hitting this
particular issue. Hopefully those that were involved in commit
a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT
core") made some effort to hunt problems down and it seems like,
maybe, the zeal robot was part of that effort? In my case, the ath11k
bug hit me and that's what I need fixed. I tried to be a friendly
citizen and also fixup ath5k because it was super obvious that it was
the same issue and the same code.
