From 0573f2c519e570d056989e57565e1ff1640dd794 Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Wed, 15 Jun 2016 11:25:43 +0800 Subject: [PATCH] usb: core: of.c: fix defined but not declare warning The helper usb_of_get_child_node is defined at of.c, but missing its declare as a global function. Fix it by adding related header file as well as compile it on conditional of CONFIG_OF.
