Subject: [PATCHv7 1/3] net: velocity: Rename vptr->dev to vptr->netdev

From: Tony Prisk <[email-masked]>
Date: Sat, 18 May 2013 14:23:43 +1200

Improve the clarity of the code in preparation for converting the
dma functions to generic versions, which require a struct device *.

This makes it possible to store a 'struct device *dev' in the
velocity_info structure.
