Revert "dma-buf: Report signaled links inside dma-fence-chain"
This reverts commit 5de376bb43
.
This change breaks synchronization of a timeline.
dma_fence_chain_find_seqno() might be a bit of a confusing name but
this function is not trying to find a particular seqno, is supposed to
give a fence to wait on for a particular point in the timeline.
In a timeline, a particular value is reached when all the points up to
and including that value have signaled.
