Note I plan to test this series on a device with a fusb302 Type-C
controller, where it broke role-swappings in a previous version of
this series. This is supposed to be fixed now but I would like to
confirm this.

I've had this on my todo list for a while now. I've
now put this in my calendar as a task for tomorrow. So please wait
till you hear back from me (hopefully with a Tested-by) with
merging this, thanks.
