The renaming of the structure seems to be unrelated to the commit message.

You are moving from allocating via plat_auto to priv_auto. So a
reasonable name for the structure would be iproc_rng200_priv.

At the end of the patch you move from plat_auto to priv_auto. So
shouldn't you call dev_get_priv(dev)?

Why do you set of_to_plat if you are using priv_auto data?
I would have expected the probe function to fill the auto allocated
private data.
