Pull drm updates from Dave Airlie:
 "This is the main drm pull request for 5.7-rc1.

  Highlights:

   - i915 enables Tigerlake by default

   - i915 and amdgpu have initial OLED backlight support

     [ Jani Nikula pipes up and points out that we've had a bunch of
       "initial support" code for a long time already, but only now
       Lyude made it actually work on real world machines ]

   - vmwgfx add support to enable OpenGL 4 userspace

   - zero length arrays are mostly removed.

  Detailed summary:
