[PATCH] usb: otg-fsm: Cancel HNP polling work when not used

We setup the HNP polling worker, but we never stop it. The OTG state machine can go round and round and keep reinitializing the worker even while it's actively running. That's bad, and debug objects catches it. Fix this by canceling the work when we leave the A_HOST or B_HOST states.

[PATCH] tcp: add an ability to dump and restore window parameters

We found that sometimes a restored tcp socket doesn't work. A reason of this bug is incorrect window parameters and in this case tcp_acceptable_seq() returns tcp_wnd_end(tp) instead of tp->snd_nxt. The other side drops packets with this seq, because seq is less than tp->rcv_nxt ( tcp_sequence()
