As I have stated before, this is not just about cleaning up pci_intx(). Again: pci_alloc_irq_vectors() USES pci_intx(), and my series does address that in its MSI patch. If you want to help, a careful review of the MSI bits would be helpful. Your patch here uses pci_intx(), you just don't see it anymore. That said, in principle it's of course possible for me to drop patches while we're still in review, but I tend to think that it's causing both you and me more work if the pci_intx() vs. pci_alloc_irq_vectors() is worked on out of all times right now. It also causes more work load for the reviewers, since they'd have reviewed my patch for nothing and would have to review yours then. Also be aware that I am not yet sure whether the devres aspect should also be removed or made more explicit in MSI. Take a look at pcim_setup_msi_release(). In the worst case you might just replace one problem with another before we figured it all out. Regards, P. > > > > Kind regards, > > Niklas > > Heiner >
