[PATCH 06/15] drm/exynos: Remove event cancelling from postclose

[Daniel Vetter]

The core takes care of this now. And since kfree(NULL) is ok we can
simplify the function even further now.

Note: There's another spin on this patch, but for different reasons,
in-flight already: http://www.spinics.net/lists/dri-devel/msg97922.html
