System hangs when FIMD registers are accessed to disable hardware overlays. This is because of the clocks which are not enabled before register access.

This patch causes regression on some exynos4210-universal_c210 devices, everything works expect colors are incorrect - it seems blue component is very dark, almost black.
Oh.... Sorry for that. I did not see any problem on 5250/5420/5800. I do not have setup for 4210. Better we should revert this patch.
Would you please help me by verifying the following patch on 4210? This is an alternate solution to the same problem.

Thanks Andrej, for bringing it to notice.
I don't see how this patch could introduce such regression, as all the affected registers seem to be properly reconfigured in fimd_win_commit() anyway.
IMHO instead of reverting the patch, this issue should be investigated and fixed properly.
Best regards, Tomasz
