Subject: [013/205] usbnet: Set parent device early for netdev_printk()

2.6.34-stable review patch.  If anyone has any objections, please let us know.

------------------


From: Ben Hutchings <ben@...adent.org.uk>

[ Upsteam commit 0dacca73a3ddefa6cb8a7e0282f938e01faa1a64 ]

netdev_printk() follows the net_device's parent device pointer, so
we must set that earlier than we previously did.
