dev->priv to netdev_priv(dev), drivers/net/tokenring/

Replacing accesses to dev->priv to netdev_priv(dev). The replacment
is safe when netdev_priv is used to access a private structure that is
right next to the net_device structure in memory.
Cf http://groups.google.com/group/comp.os.linux.development.system/browse_thread/thread/de19321bcd94dbb8/0d74a4adcd6177bd
This is the case when the net_device structure was allocated with
a call to alloc_netdev or one of its derivative.

Here is an excerpt of the semantic patch that performs the transformation

@ rule1 @
type T;
struct net_device *dev;
@@

 dev =
(
        alloc_netdev
|
        alloc_etherdev
|
        alloc_trdev
)
   (sizeof(T), ...)

@ rule1bis @
struct net_device *dev;
expression E;
@@
 dev->priv = E

@ rule2 depends on rule1 && !rule1bis  @
struct net_device *dev;
type rule1.T;
@@

- (T*) dev->priv
+ netdev_priv(dev)

PS: I have performed the same transformation on the whole kernel
and it affects around 70 files, most of them in drivers/net/.
Should I split my patch for each subnet directories ? (wireless/, wan/, etc)

Thanks to Thomas Surrel for helping me refining my semantic patch.
