> 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.
