Ooops, probably something exploded when I copied the backed-up cover- letter after regenerating the patches. Will fix. But good to see that someone actually reads cover letters :p P. > > > Juergen >

pci_intx() is a hybrid function which can sometimes be managed through devres. To remove this hybrid nature from pci_intx(), it is necessary to port users to either an always-managed or a never-managed version. xen enables its PCI-Device with pci_enable_device(). Thus, it needs the never-managed version. Replace pci_intx() with pci_intx_unmanaged().
