This patch changes fphy_status to static const, but as far as I can tell,the function is only called once during probe, and the struct is
initialized and used immediately. Since it's not reused and doesn't
need to persist beyond the function call, I don't see a clear reason
for making it static const. Is there a specific motivation behind this
change?

Thanks,
