From: Robert Foss <robert.foss@collabora.com>
As per the docs, atomic_commit should return -EBUSY "if an asycnhronous update is requested and there is an earlier update pending".
This patch is based on the rockchip patch below: http://article.gmane.org/gmane.comp.video.dri.devel/151678
Note: This patch was resent as the original submission wasn't addressed to the apparopriate recipients.
