2020-07-02dma-buf: fix dma-fence-chain out of order testLionel Landwerlin
There was probably a misunderstand on how the dma-fence-chain is supposed to work or what dma_fence_chain_find_seqno() is supposed to return. dma_fence_chain_find_seqno() is here to give us the fence to wait upon for a particular point in the timeline. The timeline progresses only when all the points prior to a given number have completed.
