Some gadget drivers may attempt to dequeue requests for an endpoint
that has already been disabled. For example, in the UVC gadget driver,
uvc_function_set_alt() will call usb_ep_disable() when alt setting 0
is selected. When the userspace application subsequently issues the
VIDIOC_STREAMOFF ioctl, uvc_video_enable() invokes usb_ep_dequeue() to
ensure that all requests have been cancelled.
bug is on uvc gadget, then. Laurent ?
We've discussed this topic a couple of months before. I believe that's not a
bug.

fair enough :-)
That's a different case, however. At the link above we're discussing
dequeueing a request which is already being dequeued. $SUBJECT is trying
to fix dequeueing of a request for an endpoint which isn't even enabled.
