I tried to build it with multi_v7_defconfig but I couldn't see any build
error.

Below is commit of linux-next tree I tested,
commit b00278812ebaae29769666ef556abc20a4680581
Merge: ad1d24c c098dc8
Author: Stephen Rothwell <sfr@canb.auug.org.au>
Date:   Fri Aug 14 12:06:53 2015 +1000

    Merge remote-tracking branch 'drm-exynos/exynos-drm/for-next


And today, I re-based exynos-drm/for-next on top of mainline. Could you
update and try to build it again?

Thanks,
Inki Dae
