Subject: Re: [PATCH] usb: xhci: Correct last context entry calculation for
 Configure Endpoint

*bump*

Sarah, Mathias, can we decide how to proceed with this? I think the
section Alan quoted is a pretty good argument in favor of my
interpretation (although of course this would not be the first time
that two sections of a spec contradict each other). But more
importantly, we have a case that just generates a clearly wrong Slot
Context right now (the one that only drops endpoints), and I see no
way how you could construct a correct Slot Context for that case with
Sarah's interpretation. We need to resolve that somehow.
