Subject: [PATCH 4.9 061/130] drm/exynos: decon5433: Fix WINCONx reset value
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Szyprowski <m.szyprowski@...sung.com>
[ Upstream commit 7b7aa62c05eac9789c208b946f515983a9255d8d ]
The only bits that should be preserved in decon_win_set_fmt() is
WINCONx_ENWIN_F. All other bits depends on the selected pixel formats and
are set by the mentioned function.
