Driver core: create devices/virtual/ tree
This change creates a devices/virtual/CLASS_NAME tree for struct devices that belong to a class, yet do not have a "real" struct device for a parent. It automatically creates the directories on the fly as needed. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
