Subject: backports: add of_find_node_by_name() if !CONFIG_OF
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5ad580451aa469ad1174e1b14b3e7f37df866752;p=openwrt%2Fstaging%2Fblogic.git

backports: add of_find_node_by_name() if !CONFIG_OF

The old kernel only exports this function when CONFIG_OF is set, but not
when CONFIG_OF is not set.
