4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> commit 3b52ce44e720c240afc4c4b03140d7b7811b23bd upstream. Since sync_pt is only allocated from a single location and is no longer the base class for fences (that is struct dma_fence) it no longer needs a generic unsized allocator.
