Thanks.
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.
