Hmm, I was assuming that, like other places in the tree, that priv was
declared void*. However, it's unsigned long in hw_random.h.
And, it looks like all users cast it. Either to a struct, or to a void
__iomem *.
So ignore what I said in my previous email. You can add my reviewed-by
without change.
It does look like /priv/ s/unsigned long/void */ would be a great
cleanup.
thx,
Jason.
