This patch fixes a memory leak in devio.c::processcompl

If writing to user space fails the packet must be discarded, as it
already has been removed from the queue of completed packets.

This patch (as1257) revises the way ehci-hcd detects STALLs.  The
logic is a little peculiar because there's no hardware status bit
specifically meant to indicate a STALL.  You just have to guess that a
STALL was received if the BABBLE bit (which is fatal) isn't set and
the transfer stopped before all its retries were used up.

The existing code doesn't do this properly, because it tests for MMF
(Missed MicroFrame) and DBE (Data Buffer Error) before testing the
retry counter.  Thus, if a transaction gets either MMF or DBE the
corresponding flag is set and the transaction is retried.  If the
second attempt receives a STALL then -EPIPE is the correct return
value.  But the existing code would see the MMF or DBE flag instead
and return -EPROTO, -ENOSR, or -ECOMM.

This patch (as1256) changes ehci-hcd and all the other drivers in the
EHCI family to make use of the new clear_tt_buffer callbacks.  When a
Clear-TT-Buffer request is in progress for a QH, the QH is not allowed
to be linked into the async schedule until the request is finished.
At that time, if there are any URBs queued for the QH, it is linked
into the async schedule.

This patch (as1255) updates the interface for calling
usb_hub_clear_tt_buffer().  Even the name of the function is changed!

When an async URB (i.e., Control or Bulk) going through a high-speed
hub to a non-high-speed device is cancelled or fails, the hub's
Transaction Translator buffer may be left busy still trying to
complete the transaction.  The buffer has to be cleared; that's what
usb_hub_clear_tt_buffer() does.

It isn't safe to send any more URBs to the same endpoint until the TT
buffer is fully clear.  Therefore the HCD needs to be told when the
Clear-TT-Buffer request has finished.  This patch adds a callback
method to struct hc_driver for that purpose, and makes the hub driver
invoke the callback at the proper time.

The patch also changes a couple of names; "hub_tt_kevent" and
"tt.kevent" now look rather antiquated.

Get rid of some obnoxious and inappropriate messaging, mostly on
DaVinci, when usbcore tries to autosuspend a root hub if just a
mini/micro-A connector is connected.  Symptom: endless stream of
messages reading like:

 musb_bus_suspend 2221: trying to suspend as a_wait_vrise is_active=1

Improve that musb bus suspend primitive a bit.  Take advantage of
this call to update the OTG state machine if appropriate, moving
the device out of the A_WAIT_VRISE state.  There's basically no
timer for that state transition just now, except with tusb6010;
that can make trouble.

Longer term, we need a better abstraction of board-specific setup in

This is an update to the "usb-ehci-update-toggle-state-for-linked-qhs"
patch.  Since an HCD's endpoint_reset method can be called in
interrupt context, it mustn't assume that interrupts are enabled or
that it can sleep.

So we revert to the original way of refreshing QHs' toggle bits.  Now
the endpoint_reset method merely clears the toggle flag in the device
structure (as was done before) and starts an async QH unlink.  When the
QH is linked again, after the unlink finishes and an URB is queued,
the qh_refresh() routine will update the QH's toggle bit.

the process of writing a linux software for such device (cressi only
provides a windows software), I patched the pl2303 linux driver to
have the interface recognized. I am submitting you the patch (very
