Merge tag 'drm-intel-fixes-2014-06-06' of git://anongit.freedesktop.org/drm-intel into drm-next
> Bunch of stuff for 3.16 still:
> - Mipi dsi panel support for byt. Finally! From Shobhit&others. I've
> squeezed this in since it's a regression compared to vbios and we've
> been ridiculed about it a bit too often ...
> - connection_mutex deadlock fix in get_connector (only affects i915).
> - Core patches from Matt's primary plane from Matt Roper, I've pushed the
> i915 stuff to 3.17.
> - vlv power well sequencing fixes from Jesse.
> - Fix for cursor size changes from Chris.
> - agpbusy fixes from Ville.
> - A few smaller things.
