From f55d17e9c3af7bf2fdb38c52a9abe4d4cfc0137c Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 4 Jan 2017 14:12:20 +0000 Subject: dma-fence: Clear fence->status during dma_fence_init() 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.
