I think the quirk functionality should be buried somewhere inside; it shouldn't be something this generic code has to worry about. > if (!ri->cfg) { > kfree(ri); > return NULL; > -- > 1.9.1 > -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Since there are platforms which have non-compliant ECAM space we need to override these accessors prior to PCI buses enumeration. In order to do that we call pci_mcfg_match_quirks() to retrieve custom pci_config_window structure. If no correlated quirk on list, use fully ECAM compliant generic PCI config accessors.
