Driver core: keep PHYSDEV for old struct class_device
Class-devices created by "struct class_device" are going to be replaced by "struct device". Keep the deprecated PHYSDEV* variables for the already "deprecated" struct class_device" devices. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
