Thanks for report.

I assume that the issue is because above patch removed 'suspended' variable
for checking the suspend status in runtime so I revived it.

I'm not sure that the change could resolve the issue. Could you test it
with the change again? I have no Exynos5800 Peach Pi board. :(

For this, I pushed it to below exynos-drm/for-next branch,
	https://git.kernel.org/cgit/linux/kernel/git/daeinki/drm-exynos.git/commit/?h=exynos-drm/for-next&id=e84f43e2b2c3388694b0b3a58c2c4447f1fbae7c

If the issue is resolved by the change then I will modify other patches for
DECON series. And if really so, there may be a corner case we missed.

Thanks,
Inki Dae
