Sorry, I've forgotten the context for this change. (We discussed
something and I suggested the right solution would be to add an
endpoint-specific data structure like a QH on the host side, but I
can't remember the details.)
Remind me please, what is the problem you need to solve?
Sure. rmmod g_ncm after ifconfig usb[01] resulted in a busy loop. The
problem was that the gadget side disabled endpoints and the host side
had requests queued. The timer found a request and gave it back with
-EPROTO because it did not find an endpoint (it was disabled). The give
back of the INT packet resulted in a re-queue. So we had another
request in the queue to process and because we did not find an endpoint
we gave it back with -EPROTO and the INT packet …
