+Subject: [PATCH] drm/vc4: hdmi: Set default state margin at reset
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Now that the TV margins are properly parsed and filled into
+drm_cmdline_mode, we just need to initialise the first state at reset to
+get those values and start using them.
