I guess that not all my message is being read, because people keep replying half-way down my messages... You can only register a struct device _once_ as a slave device. With the way you're using it here for audio, you're registering the i915 DRM device as a slave component device, and the audio side as the master. That means the audio master can bind to the DRM slave component device. You can't then have a CEC master bind to the i915 DRM slave device (it's already bound to the audio master device), and you can't register the i915 DRM device as a second slave component device. It becomes indistinguishable from the first, and there's no way to tell which of the two different 'ops' structures should be used with which master.
