With cleanup to hdmi_resources_init, we can remove hdmi_resource_cleanup
function. So could you please re-send updated patches?

You've been submitting patches into too small pieces.
Because they are trivial enough and in the same context, please merge this
kind of patches as long as they are related with the same class or topics. I
think you can combine them. :)

Thanks,
