Please check if the changelog is good to you. --- Subject: [PATCH] PCI: Skip attaching driver in device_add() We want to add pci device to device tree as early as possible but delay attach driver in next following path. To make that patch smaller, in this patch: We add match_driver field in pci_dev and default vaule is false, it will make pci_bus_match fail, so device_add will skip attaching driver, then pci_bus_attach_device() will set match_driver to true so pci_bus_match will return true and device_attach will attach driver to pci device. --- -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
