From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
of_for_each_phandle() uses of_phandle_iterator_init/next
but these aren't exported. So kernel module complile will say
ERROR: "of_phandle_iterator_init" [xxx.ko] undefined!
ERROR: "of_phandle_iterator_next" [xxx.ko] undefined!
This patch solves this issue
