I faced with same issue.
Andrzej,
Did you test this patch and worked correctly?
I had tested this patch on mainline kernel - linux
Tested on my Exynos5422 Odroid XU4, vsync seems to not happen at all,
screen remains black since kernel loads.

MIXER on Exynos5 SoCs uses different synchronisation method than Exynos4
to update internal state (shadow registers).
Apparently the driver implements it incorrectly. The rule should be
as follows:
- do not request updating registers until previous request was finished,
ie. MXR_CFG_LAYER_UPDATE_C
