So the helpfulness bar should be zero for changes that break out-of-tree stuff. Even more so this patch isn't a zero gain, the cleaner, better looking, and easier to maintain code *is* the benefit in itself. Plus we gain the ability to set mic-gain voltage with ACPI, something you couldn't do before this patch. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
