No, the tunnel feature is implemented just fine without this (and is already landed and working). It looks like the (not yet upstreamed) ec_i2c_limited_xfer for spring returns this new value directly but I'm not convinced that's technicall correct. Bill can correct me if I'm wrong, but I think this is primarily interesting once we add in cros_ec_dev (the userspace API) which needs this info. Until that happens this patch doesn't hurt and just returns some extra info. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
