Merge branch 'linux-4.10' of git://github.com/skeggsb/linux into drm-next
- Regression fix from atomic conversion (rotation on the original G80).
- Concurrency fix when clearing compression tags.
- Fixes DP link training issues on GP102/4/6.
- Fixes backlight handling in the presence of Apple GMUX.
- Improvements to GPU error recovery in a number of scenarios.
- GP106 support.
