Subject: dt: add empty for_each_child_of_node, of_find_property
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aba3dfff9a75eb272c4f47994f16eb5d548a5af1;p=linux-beck.git

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'.
