From f84d65f9b085ffbed464d1d58e8aaa8f5a2efc07 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 14 Feb 2008 16:50:34 +1100 Subject: libfdt: Fix NOP handling bug in fdt_add_subnode_namelen() fdt_add_subnode_namelen() has a bug if asked to add a subnode to a node which has NOP tags interspersed with its properties. In this case fdt_add_subnode_namelen() will put the new subnode before the first NOP tag, even if there are properties after it, which will result in an invalid blob. This patch fixes the bug, and adds a testcase for it.
