Is it possilbe to add pointer to void to unsigned short?

extern void * memcpy(void *, const void *, size_t);

unsigned char
somefunc_validate(void         *data,
                      unsigned_16   validate_entries,
                      void         *validate_cfg
                     )  {

unsigned short    min_value;


memcpy(&max_value, validate_cfg + sizeof(min_value), sizeof(max_value));

What is the result of:    validate_cfg + sizeof(min_value)

Above is working code but after compiling with upgraded compiler, following error occurs:
illegal type(s):  ptr-to-void '+' unit
