4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Chris Wilson <[email protected]> commit 83dd1376fd92f33bdeca9e83d479534a4e7f870b upstream. As the fence->status is an optional field that may be set before dma_fence_signal() is called to convey that the fence completed with an error, we have to ensure that it is always set to zero on initialisation so that the typical use (i.e. unset) always flags a successful completion.
