Pull drm fixes from Dave Airlie:
 "Fairly quiet, a couple of i915 fixes, one dma-buf fix, one vc4 and two
  sun4i changes

  dma-buf:
   - Single null pointer deref fix

  i915:
   - Fix selftest reference to stack data out of scope
   - Fix GVT null pointer dereference

  vc4:
   - fill asoc card owner

  sun4i:
   - program secondary CSC correctly"
