Currently the driver explicitly clears the HWO bit of the TRB
prepared for short packet or ZLP for EPs in both the directions,
and returns with non-zero code which breaks cleanup of completed
requests. The driver does this because it is written with the
understanding that the HW does not clear HWO for such packets.
But the databook section 4.2.3.2 says that the HW does not clear
HWO for such packets on the OUT EP only.
Now consider a device-to-host(USB IN) usecase like SW NCM, where
the u_ether driver looks for interrupt on every 5th request(say).
In between these 5 requests, if there is any packet of multiple
of MPS, then ZLP TRB will also be prepared. When the event is
received for the 5th request, we will only handle upto the ZLP
TRB because of the faulty logic described above. And only on the
event for the 10th request, we handle the 5th request (because of
IOC set on the 5th request). So, clearly the TRB cleanup logic is
lagging behind the HW actually completing the requests. When this
mismatch happens multiple times, there eventually comes a time
when the SW does not have any free requests anymore and hence
stall will be seen.
Fix this by returning with non-zero code only if the IOC bit is
set for the short packet or ZLP TRB, so that the cleanup routine
continues upto the TRB for which the event was raised.

Commit 3741fb2cfb ("coresight: byte-cntr: Free USB requests when
disconnected") introduced a regression which leads qdss_disable &
qdss_close paths to race between them.
If qdss_disable path is processing, it would queue disconnect_work
which will notify the bypass notifier of USB_DISCONNECT and it will
call free_req. Within same time frame if qdss_close is called,
it will try to go ahead dequeue the request and wait_for_completion.
But since free_req got called, it will free the qreq instance which
wait_for_completion uses resulting in kernel panic.
Fix this by checking for ep_dequeue status if dequeue was success
then only wait_for_completion. Also taking the list operation under
qdss->lock in order to avoid any races between qdss_write as well.
