This patch looks fine to me, but I did have one small question.
What is the thinking behind punting this to the machine driver?

I guess you can not register it if there is no jack present
on the board, or if you have multiple jacks name them
meaningfully. Although I sort of feel like those applied to
the old extcon approach that just internally registered all
the interfaces.

But to be clear not asking for any changes just more about trying
to refine my understanding of things.

Thanks,
Charles
