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.

    Doesn't get described as well. I think you're mixing two types of changes 
in one patchset.

Agreed, you're going to have to redo this entire patch set.

We can use the wrapper functions platform_{get,set}_drvdata() instead of
dev_{get,set}_drvdata() with &pdev->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.
