Still some nits, sorry.

I probably wouldn't have been so picky if I hadn't have found the unused enum.

I don't know what it is about the "no ..." comments that I don't like.

"INTB IRQ not configured" just sounds more professional.

Your other errors start with an uppercase char.  Consistency.

"Failed to ..." like everywhere else.

"INTB IRQ chip", it's not a variable and this is user facing.

Why the question mark?  What are you unsure about?

Why doesn't -EPROBE_DEFER work for this?
