Bas Nieuwenhuizen 2737d0bc21 drm/syncobj: Deal with signalled fences in drm_syncobj_find_fence. ... commit b19926d4f3 upstream. dma_fence_chain_find_seqno only ever returns the top fence in the chain or an unsignalled fence. Hence if we request a seqno that is already signalled it returns a NULL fence. Some callers are not prepared to handle this, like the syncobj transfer functions for example. This behavior is "new" with timeline syncobj and it looks like not all callers were updated. To fix this behavior make sure that a successful drm_sync_find_fence always returns a non-NULL fence. v2: Move the fix to drm_syncobj_find_fence from the transfer functions.
