This patch changes acpi_bus_scan() to take an acpi_handle rather than an acpi_device pointer. I plan to use acpi_bus_scan() in the hotplug path, and I'd rather not assume that notifications only go to nodes that already have acpi_devices. This will also help remove the special case for adding the root node. We currently add the root by hand before acpi_bus_scan(), but using a handle here means we can start the acpi_bus_scan() directly with the root even though it doesn't have an acpi_device yet. Note that acpi_bus_scan() currently adds and/or starts the *children* of its device argument. It doesn't do anything with the device itself. Signed-off-by:
