Re: [RFC PATCH 0/1] media: uvcvideo: reset interface on bulk stream stop

I tested 25e531b422dc ("usb: xhci: Make usb_host_endpoint.hcpriv
survive endpoint_disable()") on the affected setup, and it fixes the
issue.

With that change applied, repeated stop/start cycles complete
successfully, and I no longer see the uvcvideo -71 transfer errors.

So I think the uvcvideo workaround in this RFC is not needed. The issue
is covered by the xHCI fix.

Thanks,
Henry
