Hi desperado,
A few different ways to do this you could slide a bit of timber between the frame and the lintel, fixing it up through the door frame leaving enough room to fix a strip of plasterboard either side.
You could pack it out with plasterboard laying them flat above door and filling out one side and waiting for it to cure before doing the other side,
Fill it in with compo or browning.
Good Luck
