If anyone has any objections, please let me know. ------------------ From: Lu Yao [ Upstream commit 31643dc89818d9b65bf42ecb1c67c99b64146fba ] If dma_fence_chain_find_seqno() failed once, 'err' will store val in the following loop. May causing returns '-EINVAL' even though that entry never called dma_fence_chain_find_seqno() at all.
