These come from a newer version of cm32181.c, which is floating around the net, with a copyright of: * Copyright (C) 2014 Capella Microsystems Inc. * Author: Kevin Tsai <ktsai@xxxxxxxxxxxxxxxx> * * This program is free software; you can redistribute it and/or modify it * under the terms of the GNU General Public License version 2, as published * by the Free Software Foundation. Note that this removes the bogus CM32181_CMD_ALS_ENABLE define, there is no enable bit, only a disable bit and enabled is the absence of being disabled. This is a preparation patch for adding support for the older CM3218 model of the light sensor.
