+Clean up checks for already prepared/enabled in panels
+------------------------------------------------------
+
+In a whole pile of panel drivers, we have code to make the
+prepare/unprepare/enable/disable callbacks behave as no-ops if they've already
+been called. To get some idea of the duplicated code, try::
+
+  git grep 'if.*>prepared' -- drivers/gpu/drm/panel
+  git grep 'if.*>enabled' -- drivers/gpu/drm/panel
+
+In the patch ("drm/panel: Check for already prepared/enabled in drm_panel")
+we've moved this check to the core. Now we can most definitely remove the
+check from the individual panels and save a pile of code.
+
+In adition to removing the check from the individual panels, it is believed
+that even the core shouldn't need this check and that should be considered
+an error if other code ever relies on this check. The check in the core
+currently prints a warning whenever something is relying on this check with
+dev_warn(). After a little while, we likely want to promote this to a
+WARN(1) to help encourage folks not to rely on this behavior.
