It took me a while to parse exactly what you're doing here. - In pnv_ioda_setup_dev_PE(), we take a reference on the pci_dev, this is to protect a pointer in the pci_dn structure, but not to protect the pointer in the pci_dev structure (which doesn't need to be protected by taking a reference, because the lifetime of the pnv_ioda_pe is the same as the pci_dev). - The pointer in the pci_dn structure has now been removed, so we should remove the pci_dev_get() accordingly.Correct. Did I do such a bad job explaining it in the commit message that I need to rephrase?
