This works, but I thought that the point of the recent patch was to make the driver modular.
You said: "commit 5779a072c248db7a40cfd0f5ea958097fd1d9a30 removed the =y. so it could be built as a module."
That's not the same as what is happening here.
I think it would be better to revert the commit mentioned above.
