+Subject: [PATCH] drm: rcar-du: Set primary plane zpos immutably at
+ initializing
+
+This patch backports a fix from [1] for an issue occurs on Weston 8.0.0.
+
+[1]:
+https://lists.freedesktop.org/archives/dri-devel/2020-April/261224.html
+
+According to drm_plane_create_zpos_property() function documentation,
+all planes zpos range should be set if zpos property is supported.
+However, the rcar-du driver didn't set primary plane zpos range. Since
+the primary plane's zpos is fixed, set it immutably.
