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