That function sometimes implicitly uses devres for automatic cleanup. We should get rid of this implicit behavior. To do so, a pci_intx() version that is always-managed, and one that is never-managed are provided. Then, all pci_intx() users are ported to the version they need. Afterwards, pci_intx() can be cleaned up and the users of the never-managed version be ported back to pci_intx(). This way we'd get this PCI API consistent again. The last patch obviously reverts the previous patches that made drivers use pci_intx_unmanaged(). But this way it's easier to review and approve. It also makes sure that each checked out commit should provide correct behavior, not just the entire series as a whole. Merge plan for this would be to enter through the PCI tree. Please say so if you've got concerns with the general idea behind the RFC. Regards, P.
