By not having the attributes in the first place, this limitation can be avoided altogether. The IRQ attributes are mostly used for printing ('info qtree') and there is one user, hw/ppc/pnv, to use the attributes directly. As it turns out, the printing is redundant if the IRQ numbers are exposed as QOM properties and hw/ppc/pnv can be easily ported away. The patch series is structured as follows: Patch 1-3 QOM'ify the last devices which rely on printing their IRQ numbers via the ISADevice attributes. Patch 4 and 5 remove the last users of the ISADevice attributes such that they can be removed in patch 6. The remainder of the patch series is cleanup. Patch 6 turns isa_init_irq() into a trivial wrapper for isa_get_irq(). That is, the former function becomes redundant. All users are therefore converted to use isa_get_irq() directly. Finally, the last patch removes the now unused isa_init_irq().
