[alsa-devel] [PATCH] base: export symbol of_phandle_iterator_init/next

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

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
