It's always best to check MAINTAINERS to see the current support status. In this case it has a section to pick up those Wolfson drivers, with the correct email address. The list email will be monitored by multiple people. WOLFSON MICROELECTRONICS DRIVERS L: patches@opensource.cirrus.com S: Supported <SNIP> F: include/sound/wm????.h <SNIP> F: sound/soc/codecs/wm*

Even though we had the wm8978 driver for some time and a number of boards using it already, we never had a binding for it. Let's add it based on what the driver expects and the boards are providing.
