[PATCH 2/8] net: ucc_geth: use platform_{get,set}_drvdata()

From: Libo Chen <hidden>
Date: 2013-08-12 13:25:01 

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

[PATCH RESEND 2/8] net: ucc_geth: use platform_{get,set}_drvdata()

From: Libo Chen <hidden>
Date: 2013-08-14 03:39:53 

We can use the wrapper functions platform_{get,set}_drvdata() instead of
dev_{get,set}_drvdata() with &ofdev->dev, it is convenient for user.

Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.
