Should this be also a fix?

This only comes into play when switching alt-modes, so more
or less the same as with the displayport altmode fix:

"There are no users if this yet, until we've agreement
on the DT bindings and code merged for adding alt-modes
to an usb-connector node, nothing will be using this code,
so I see little use in adding a Cc: stable or some such."

Regards,

Hans
