Watch http://source.winehq.org/patches/ for your patch's status (see legend at bottom).
It might be rejected since it doesn't actually fix any behavioral problem in Wine. IIRC trivial cleanups in code are frowned upon, especially if they cross many modules. Better to pick some small real problem and fix it. How about http://bugs.winehq.org/show_bug.cgi?id=32922 ?
