Rob is indeed mistaken here, but please let's keep things civil. I
did write the patches to remove the hint, but I avoided merging them
because I think they are risky. I wanted to get the core irq_domain
changes in first. The removal of hint will be applied during the next
merge window.

I will take your bug fix and get it pushed up to Linus soon.
