Now that there is no public drvdata() accessor anymore, all bus device private
data accesses go through the bus abstraction.

So, you could go back to your original approach and wrap the state in a bus
specific bus device private data wrapper type, which would also get you rid of
the rust_private_data pointer you add to struct serdev_device.
