By applying the very same patch perhaps?

Currently all parameters in 'affd' are read-only, so 'affd' is marked
as const in both pci_alloc_irq_vectors_affinity() and
irq_create_affinity_masks().
We have to ask driver to re-caculate set vectors after the whole IRQ
vectors are allocated later, and the result needs to be stored in 'affd'.
