Merge branch 'linux-4.10' of git://github.com/skeggsb/linux into drm-next
- GP102/GP104 devinit (suspend/resume, optimus) hang fix
- GP102/GP104 hardware cursor fix
- Fix for a regression on some non-MST monitors that was caused by the
MST work
- Workaround for certain laptops where ACPI sends display hotkey presses
on a modeset, causing gnome-settings-daemon to go into a continuous loop
