Yes, that might be a possible solution, albeit I don't like it - it points
out that the original patch from Joby is - beyond the bug here - at
least inefficient (in that we'd then allocate an entry per MSI-X table
entry, i.e. per IRQ, instead of per device). I therefore think we
rather ought to revert that change, and have him redo it properly.
