That is for hotplug handling: .add need to return early to make sure all acpi device could be created and added early. So .start could device_add pci device that are found in acpi_pci_root_add/pci_acpi_scan_root(). That is holding pci devics to be out of devices for while. We could use bus notifier to handle hotplug case. CONFIG_HOTPLUG is enabled always now. Need to add drivers_autoprobe bit in acpi_device to hold attaching drivers for acpi_devices, so could make sure all acpi_devices get created at first. Then acpi_bus_attach() that is called from acpi_bus_add will attach driver for all acpi_devices that are just created. That make the logic more simple: hotplug path handling just like booting path that drivers are attached after all acpi device get created. At last we could remove all acpi_bus_start workaround. Thanks Yinghai Yinghai Lu (4): ACPI: add drivers_autoprobe in struct acpi_device ACPI: use device drivers_autoprobe to delay loading acpi drivers PCI, ACPI: Remove not used acpi_pci_root_start() ACPI: remove acpi_op_start workaround drivers/acpi/pci_root.c | 27 +++------ drivers/acpi/scan.c | 145 ++++++++++++++++++++++------------------------- include/acpi/acpi_bus.h | 9 +--- 3 files changed, 77 insertions(+), 104 deletions(-) -- 1.7.7 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
