This function is more complicated than it needs to be because of the
consts. It's not worth saving them because we drop the consts anyway
when we return (void *)name_ptr.

You could simplify it further by keeping one of the consts:
static void *comedi_recognize(struct comedi_driver *driv, const char *name)
{
unsigned i;
const char **name_ptr = driv->board_name;
for (i = 0; i < driv->num_names; i++) {
if (strcmp(*name_ptr, name) == 0)
return name_ptr;
name_ptr = (void *)name_ptr + driv->offset;
}
return NULL;
}
