The patch below should help with joysticks attached to gameports;

Input: gameport - fix attach driver code

The commit 6902c0bead4ce266226fc0c5b3828b850bdc884a that moved
driver registration out of kgameportd thread was incomplete and
did not add the code necessary to actually attach driver to
already registered devices, rectify that.
