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)

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 missed the patch "ARM: dts: remove display power domain for
exynos5420" in linux-samsung-soc mail thread.
In my test without power domain property, the exynos5420 dsi master
driver works well.
I applied this merge fix patch:
