+Subject: [PATCH 3/3] [MMFMWK-7567] kmssink: check scaleable when set_caps
+
+when video size is same as display resolution, show frame will not do
+retry because the setplane will never fail. But the scale result is not
+correct. We can do this check by set a fake plane.
+
+Upstream-Status: Inappropriate [i.MX specific]
