If we call extcon_register_notifier() with the wrong cable type,
it blows up with an oops instead of returning an error code.
Let's be nice and fail gracefully given that the consumer might
not know if the cable is supported by the extcon provider.

This patch has some merge conflict because the base branch is not on linux-next.
But, Looks good to me. I applied it manually on extcon-next branch.

Thanks,
