Yes but I think I saw this other patch set from Lee, hitting
irqdomain, OF and MFD to actually fix this ... or did I get
it wrong?
No, you're not wrong.
Historically (in my patches) xb8500_irq_get_virq() was used by drivers
to obtain a VIRQ when not using Device Tree. Now the MFD core handles
conversion there is little requirement for it. In fact there are no
more users for db8500_irq_get_virq() and only one user for 
ab8500_irq_get_virq() and that's itself. I guess we can rid them and
call irq_get_mapping() directly instead.
Oh dear.  Unfortunately whoever added this support to the MFD core did
so in such a manner that it's only supported for device tree systems
and only for devices which express the MFD cells as device tree nodes
which means that most devices can't it - db8500 has got a reasonably
unusual combination there.
