It certainly *looks* goofy this way, and if it's not
buggy today then it'll probably grow some in the future.
Whoops, I see. The answer should have been in a comment;
Thank goodness. I hoped that I hadn't spent the time writing the

I'll fix that and send to Greg.
Answer to my question: because one branch must advance
the bulk or control queue the endpoint was on, but the
other branch doesn't.
Yes. The other branch also must not call musb_giveback() because thel
latter assumes to be called on active qh and will e.g. spoil the saved
toggle state otherwise.
