I don't think is correct. The incoming handle is in shared_handle, not
in handle. Once the code block around line 310 has executed,
shared_handle is the handle produced by drmPrimeFDToHandle, and closing
it on error (as the code currently does) should be the correct thing to do.
The only possible issue is that I'm seeing is that perhaps the handle
should be closed _before_ the unlock. Maybe someone else knows the details.
Cheers,
Nicolai
