4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Boris Brezillon <boris.brezillon@bootlin.com>
commit 9a0e9802217291e54c4dd1fc5462f189a4be14ec upstream.
When using uni-planar formats (like RGB), the scaling parameters are stored in plane 0, not plane 1.
