4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Brian Starkey <brian.starkey@xxxxxxx>
[ Upstream commit 7916efe5b57505080b3cebf5bdb228b4eda008ea ]
The horizontal and vertical flip flags were the wrong way around,
causing reflect-x to result in reflect-y being applied and vice-versa.
Fix them.
Fixes: ad49f8602fe8 ("drm/arm: Add support for Mali Display Processors")
