2004 * and result fields from struct cmd_ds_gen)
2005 * @param cmd_size size structure pointed to by cmd
2006 * @param rsp pointer to an area where the result should be placed
2007 * @param rsp_size pointer to the size of the rsp area. If the firmware
2008 * returns fewer bytes, then this *rsp_size will be
2009 * changed to the actual size.
2010 * @return -1 in case of a higher level error, otherwise
2011 * the result code from the firmware
