Do you have the hardware that this driver controls?

Does that show anything?

Then there's a bug to fix in the driver, it must not clean up everything
properly.  Based on a quick read of it, there is lots of things that
need to be fixed in it, that's why it is in staging.  If you are
interested, I would suggest fixing this issue would be a great start.

good luck!
