Hi!

commit 173ee3962959a1985a109f81539a403b5cd07ae7 upstream.

Commit f42b0e18f2e5 ("of: add node name compare helper functions")
failed to add the module exports to of_node_name_eq() and
of_node_name_prefix(). Add them now.

Fixes: f42b0e18f2e5 ("of: add node name compare helper functions")

Fixes build failure for multi_v7_defconfig

Ok, what is going on here?

I don't believe f42b0e18f2e5 causes build failure; it adds functions,
but it can't cause build failure without a user.

Which commit fails the build? Do we have that in 4.4.y-cip? Can
this be placed before the buggy commit so that build is not broken?
For multi_v7_defconfig I get this below build error:

ERROR: "of_node_name_eq" [drivers/gpu/drm/rcar-du/rcar-du-drm.ko] undefined!
scripts/Makefile.modpost:91: recipe for target '__modpost' failed
make[1]: *** [__modpost] Error 1
Makefile:1161: recipe for target 'modules' failed
make: *** [modules] Error 2

commit eeaa48eee492d ("drm: rcar-du: Support panels connected directly to the DPAD outputs") fails the build which was added in 4.4-cip kernel.

Cheers,
Prabhakar
