It's not quite correct, because OMAP4 has issues in this area as well (which does select IRQ_DOMAIN but can be without OF.) The result is an oops from irq_domain_add() because domain->ops is NULL.
The right solution is three fold:
1. Wrap the bits of code in CONFIG_IRQ_DOMAIN 2. Get rid of the #ifdef CONFIG_OF there, so the 'ops' member can be initialized. 3. Fix the OMAP vp code not to oops when voltdm->pmic is NULL
which I have in my combined patch for fixing OMAP so far.
It'd also help if we supported null ops, I sent patches for that a few times over the 3.3 cycle since I was running into it on my systems but apparently to /dev/null and further changes in this area have made the patches not apply any more.
