Subject: linux-next: build failures after merge of the drm tree

Hi Dave,

After merging the drm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: "drm_sysfs_connector_remove" [drivers/gpu/drm/i2c/tda998x.ko] undefined!
ERROR: "drm_sysfs_connector_add" [drivers/gpu/drm/i2c/tda998x.ko] undefined!

Caused by commit c707c3619ca8 ("drm/i2c: tda998x: add component
support") interacting with commit 34ea3d386347 ("drm: add register and
unregister functions for connectors").  Maybe it should have been fixed
up in the merge commit 920f946428b7 ("Merge branch 'tda998x-devel' of
git://ftp.arm.linux.org.uk/~rmk/linux-cubox into drm-next")?

I reverted commit c707c3619ca8 for today.

But then the arm multi_v7_defconfig build produced these errors:

ERROR (phandle_references): Reference to non-existent node or label "disp_pd"

ERROR: Input tree has errors, aborting (use -f to force output)
make[2]: *** [arch/arm/boot/dts/exynos5420-arndale-octa.dtb] Error 2

make[2]: *** [arch/arm/boot/dts/exynos5800-peach-pi.dtb] Error 2
ERROR: Input tree has errors, aborting (use -f to force output)

Caused by commit 5a8da524049c ("ARM: dts: exynos5420: add dsi node")
interacting with commit d51cad7df871 ("ARM: dts: remove display power
domain for exynos5420") from the arm-soc tree.

I applied this merge fix patch:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Tue, 5 Aug 2014 13:03:01 +1000
Subject: [PATCH] ARM: dts: exynos5420: remove disp_pd

per comit d51cad7df871 ("ARM: dts: remove display power
domain for exynos5420").
