drivers/usb/misc/sisusbvga/sisusb.c: In function sisusb_open
drivers/usb/misc/sisusbvga/sisusb.c:2444: warning: sisusb is used uninitialized in this function

is a genuine bug (which will cause oops). We cannot use "sisusb" in
error path for (!interface), because sisusb will itself be derived
from "interface" later.

the iuu_phoenix driver submits another URB from a completion handler.
This dictates a certain order of calls to usb_kill_urb() in kill_traffic().
As other drivers may do it the other way round, we need to use both
orders in kill_traffic().
This patch does so and should be merged before iuu_phoenix is merged.

Some usb-serial devices (e.g. certain Edgeport models) have more than
one serial port on the same USB device/interface.

Currently the only way to distinguish these ports in userspace is by
their minor device number: the driver makes them consecutive and in
stable order.

However, for the purpose of stable naming with udev this is
insufficient: when udev handles the ADD event for one of the ports it
doesn't know what minor number the other one has.

To make stable naming easier, export the port number via sysfs.

This patch (as972) changes ohci-hcd so that after an error occurs, the
remaining TDs for the URB will be skipped over entirely instead of
going through the donelist.  This enables the driver to give back the

error status in urb->status.

store the status of unlinked URBs since we can't use urb->status for
that purpose any more.  To help simplify the HCDs, usbcore will check
urb->unlinked before calling the completion handler; if the value is
set it will automatically override the status reported by the HCD.

This patch (as969) continues the ongoing changes to the way HCDs
report URB statuses.  The programming interface has been simplified by
making usbcore responsible for clearing urb->hcpriv and for setting
-EREMOTEIO status when an URB with the URB_SHORT_NOT_OK flag ends up
as a short transfer.

By moving the work out of the HCDs, this removes a fair amount of
repeated code.

This patch (968) changes the way uhci-hcd reports status for
Isochronous URBs.  Until now urb->status has been set to the last

descriptors.  So this patch removes the extra computation and makes
uhci-hcd behave like the others.

It is not necessary to powerdown the ports on ehci_pci_reinit() when the
chip reset already did that.  Removing this saves 20ms during restart
after poweroff paths (which OLPC uses a lot).

To ensure driver startup then behaves consistently, force a reset during
driver startup.  (Not doing this was an accident of some previous changes
to the init sequence.)

Make the corresponding change in the PS3 support.  It's not clear what
ehci-fsl should do here; it has similar code to the PS3.
