This code does:

spin_unlock_irqrestore(&udc->lock, flags);
which does not make sense. In theory, the first unlock could enable
IRQs and then the second _irqrestore could disable them again. There
would be a brief momemt where IRQs were enabled improperly.
In real life, however, this function is always called with IRQs enabled
and the bug does not affect runtime.

It generally doesn't make sense to use _irq() and _irqsave() in the same
function because either some of the callers have disabled IRQs or they
haven't. In this case, the v_recv_cmd_submit() appears to always be
called with IRQs enabled so the code works fine. That means I could
convert it to either _irq() or _irqsave() but I chose to use _irqsave()
because it's more conservative and easier to review.
