On normal loop completion, dma_fence_unwrap_next()\nreleases this via dma_fence_chain_walk() -> dma_fence_put().\n\nWhen virtio_gpu_do_fence_wait() fails and the function returns early\nfrom inside the loop, the cursor->chain reference is never released.\nThis is the only caller in the entire kernel that does an early return\ninside dma_fence_unwrap_for_each.\n\nAdd dma_fence_put(itr.chain) before the early return."
