[PATCH] dev->priv to netdev_priv(dev), for drivers/net/wireless
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.
