That changelog is not very descriptive. By the time a patch is reposted, the original reviewer may well have forgotten what comments they made, and nobody else is going to remember since they didn't make the comments. In other words, it's better to explicitly describe the changes that were made, rather than who requested them. -- 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
