Yes, this commit breaks all drivers using devm* for IRQ management on
OF-based systemsi because devm* cleanup happens in device code, after
bus's remove() method returns. I'd recommend reverting and finding a
better way (making cleanup a custom devm action as well?).

Ouch, my bad.

Wolfram, any opinion ? The original patch fixes a real bug, so we shouldn't 
just revert it.

I guess the usual rules apply. Let's try to fix it for v4.0, otherwise I
have to revert it.
