Subject[PATCH] dt: add empty for_each_child_of_node, of_find_property
The patch adds a couple empty functions for non-dt build, so that
drivers migrating to dt can save some '#ifdef CONFIG_OF'.

Signed-off-by: Stephen Warren <>
Unfortunately, I screwed up and my recent sdhci-tegra.c changes rely on this
change to compile without CONFIG_OF; I really need to stop doing my test-
builds in a single branch will all my outstanding changes present:-(
