Technically you're not "allowing" runtime PM, you just stop keeping the device runtime active. A more fitting subject might thus be: PCI/PM: Keep devices runtime active during enumeration > --- a/drivers/pci/pci-driver.c > +++ b/drivers/pci/pci-driver.c > @@ -1278,6 +1278,9 @@ static int pci_pm_runtime_suspend(struct device *dev) > pci_power_t prev = pci_dev->current_state; > int error; > > + if (WARN_ON(!pci_dev_is_added(pci_dev))) > + return -EBUSY; > + If this can't happen (as the commit message says), why warn? Thanks, Lukas
