Pull drm fixes from Dave Airlie:
 "Misc fixes for v4.11-rc1.

  This is a selection of fixes for recent bugs, the vmwgfx one is
  important to avoid a regression, and compat ioctl one is pretty urgent
  for stable. Otherwise nothing too much.

  I've got a separate pull req for some AST hw IBM need to enable"

* tag 'drm-fixes-for-v4.11-rc1' of git://people.freedesktop.org/~airlied/linux:
  dma-buf: add support for compat ioctl
  drm/vmwgfx: Work around drm removal of control nodes
  drm/rockchip: cdn-dp: Fix error handling
  drm/rockchip: add extcon dependency for DP
  drm: zte: fix static checker warning on variable 'fmt'
