possible event_space corruption with ipp_get_event()?

[Rob Clark]

Hey Inki,

Could you or one of the exynos folks have a look at ipp_get_event()?
That handling of file_priv->event_space looks rather suspect.  I don't
see where event_space is decremented in the first place.  I'm not sure
if that is just broken, or if there is something subtle going on.. but
I guess it probably either needs fixing or a comment.

BR,
