From ae0b5908de3b9855f8931bc9b32c9fc4962df5a9 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 12 Feb 2008 11:58:31 +1100 Subject: libfdt: Add and use a node iteration helper function. This patch adds an fdt_next_node() function which can be used to iterate through nodes of the tree while keeping track of depth. This function is used to simplify the iteration code in a lot of other functions, and is also exported for use by library users.
