+Subject: [PATCH 4353/4736] drm/amd/display: optimize bandwidth after commit
+ streams.
+
+[Why]
+System is unable to enter S0i3 due to DISPLAY_OFF_MASK not asserted
+in SMU.
+
+[How]
+Optimized bandwidth should be called paired and to resolve unplug
+display underflow issue, optimize bandwidth after commit streams is
+moved to next page flip, in case of S0i3, there is a change for no
+flip coming causing display count is 1 in SMU side.
+Add optimize bandwidth after commit stream.
