   4 Subject: [PATCH] drm/vc4: hdmi: Use debugfs private field
   5
   6 We're calling vc4_debugfs_add_file with our struct vc4_hdmi pointer set
   7 in the private field, but we don't use that field and go through the
   8 main struct vc4_dev to get it.
   9
  10 Let's use the private field directly, that will save us some trouble
  11 later on.
