Hi guys, as pointed out by Chia-I userspace doesn't see any progress when signaling is not enabled and Boris noted that this is because dma_fence_array_signaled() never returns true in this case. Improve this by fixing the dma_fence_array_signaled() implementation to also return true even if signaling was never explicitely enabled. We should probably adjust the documentation as well that when the callback is implemented it should make progess visible even without enabling signaling. Please test and review, Christian.
