Depends which bug you are talking about. I'd fix the bug with the char
dev file open which requires both taking a reference to the controller
and a reference to the transport module. Might as well do both in one patch.

Then I'd fix the bug with the passthru reference to the controller by
taking a reference to the module in that path somehow.
