class: rename "devices" to "class_devices" in internal class structure
This renames the struct class "devices" field to be "class_devices" to make things easier when struct bus_type and struct class merge in the future. It also makes grepping for fields easier as well. Based on an idea from Kay. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
