[drm/exynos-fimd] Display regression in v3.12-rc1

Hi Andrzej ,

I was testing the latest Linux kernel release (v3.12-rc1) on Exynos4210 based Origen board. I found a display regression with that. I do not get any display on the LCD (other than backlight) with the latest kernel. Git bisect pointed me to the following commit: 111e6055d4e0d35c6a4b6cd37d7bb00a88eaffb4 ("drm/exynos: fimd: replace struct fb_videomode with videomode"). Reverting this patch does not cause the issue. Let me know if you need any other info to help identify the problem.
