Subject: net: convert print_mac to %pM

This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

Subject: CRED: Wrap task credential accesses in the USB driver

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.

Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

Change some task->e?[ug]id to task_e?[ug]id().  In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be
addressed by later patches.

2.6.26(.x, cannot remember) could handle the microSD card in my Nokia

Add the identifiers for the Sprog II USB. This is a DCC control interface
using the FTDI-SIO hardware: http://www.sprog-dcc.co.uk/. People have been
using it with insmod options for ages, this just puts it into the driver
data.

The following patch adds in the USB PID for Ewert Energy System's CANdapter
device (CANBUS to USB-Serial which uses the FTDI 245R chipset) to the ftdi_sio
device driver.

The patch was tested successfully on Linux kernel 2.6.27 under Ubuntu.

Subject: USB: skip Set-Interface(0) if already in altsetting 0

When a driver unbinds from an interface, usbcore always sends a
Set-Interface request to reinstall altsetting 0.  Unforunately, quite
a few devices have buggy firmware that crashes when it receives this
request.

To avoid such problems, this patch (as1180) arranges to send the
Set-Interface request only when the interface is not already in
altsetting 0.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This implements the Nokia vendor-specific communication device class
function to exchange Phonet messages over USB. This function is already
found in the "PC suite" USB profile of (non-Linux) Nokia handsets.
