+Subject: [PATCH] drm/atomic: Add a function to reset connector TV
+ properties
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Commit 731514b446fe6748d5a55a3dff202efb45c7d8df upstream.
+Reworked as functions have been moved from drm_atomic_helper.[c|h]
+to drm_atomic_state_helper.[c|h].
+
+During the connector reset, if that connector has a TV property, it needs
+to be reset to the value provided on the command line.
+
+Provide a helper to do that.
