Thanks for your patch, but I can't figure out exactly what problem you're solving. There is only one definition of PCI_VENDOR_ID_SUNIX in the current upstream tree, so I don't see what the conflict is. If there's a conflicting definition in some out-of-tree driver, we generally wouldn't change the upstream tree, we'd ask you to change the out-of-tree driver. Or even better, to merge your driver into the upstream kernel so it's no longer maintained out of the tree.
