    ACPI: call init_acpi_device_notify() explicitly rather than as initcall · 0e46517d
    Bjorn Helgaas authored
    This patch makes acpi_init() call init_acpi_device_notify() directly.
    Previously, init_acpi_device_notify() was an arch_initcall (sequence 3),
    so it was called before acpi_init() (a subsys_initcall at sequence 4).
    
    init_acpi_device_notify() sets the platform_notify and
    platform_notify_remove function pointers.  These pointers
    are not used until acpi_init() enumerates ACPI devices in
    this path:
    
        acpi_init()
    	    acpi_scan_init()
    		acpi_bus_scan()
    		    acpi_add_single_object()
    			acpi_device_register()
    			    device_add()
    				<use platform_notify>
    
    So it is sufficient to have acpi_init() call init_acpi_device_notify()
    directly before it enumerates devices.
