+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] drm/panel: st7703: Rename functions from jh057n prefix to
+ st7703
+
+This is done so that code that's not specific to a particular
+jh057n panel is named after the controller. Functions specific
+to the panel are kept named after the panel.
