[PATCH v7 00/11] PRIME Synchronization

[Alex Goins]

Hello all,

This patch set fixes the lack of NULL checking and the leaks in the blacklisting
patches, and changes the UDL blacklist to a generic USB transport blacklist,
reflecting that there are other USB transport DRM drivers with similar
limitations to UDL.

These patches change the xserver to support setting up PRIME with double
buffering, and implement double buffered PRIME sink and source support in
the modesetting driver. In addition to these changes, I've upstreamed a
couple of patches to the i915 DRM driver that mesh with these, and have
implemented double buffered PRIME source support in the NVIDIA proprietary
driver (pending release.)
