Merge tag 'drm-fixes-for-v4.15-rc5' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "I've got most of two weeks worth of fixes here due to being on
  holidays last week.

  The main things are:

  - Core:
     * Syncobj fd reference count fix
     * Leasing ioctl misuse fix

   - nouveau regression fixes

   - further amdgpu DC fixes

   - sun4i regression fixes

  I'm not sure I'll see many fixes over next couple of weeks, we'll see
  how we go"
