4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Lucas Stach <l.stach@xxxxxxxxxxxxxx> [Fixed differently in 4.10] The fence needs to be cleared out, otherwise the following commit might wait on a stale fence from the previous commit. This was fixed as a side effect of 9626014258a5 (drm/fence: add in-fences support) in kernel 4.10. As this commit introduces new functionality and as such can not be applied to stable, this patch is the minimal fix for the kernel 4.9 stable series.
