[PATCH 3/5] GenWQE: Ensure rc is not returning an uninitialized value

From: Frank Haverkamp
Date: Thu Mar 20 2014 - 10:11:46 EST

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

rc is not initialized, so genwqe_finish_queue() either returns -EIO or
garbage. Fortunately the return is not being checked by any callers,
so this has not yet caused any problems. Even so, it makes sense to
fix this small bug in case is is checked in future.
