+Subject: [PATCH 2625/4131] drm/amd/display:: Fix NULL pointer in Raven hotplug
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Programming sequence to frontend and backend has been switched.
+In such case, program_scaler() is gettingĀ called when programming
+frontend, and should be removed from backend programming routine.
