From 5063e25a302e6a83f6590d9a06bd5f6400b17430 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Fri, 3 Oct 2014 16:28:27 +0100 Subject: of: Eliminate of_allnodes list The device tree structure is composed of two lists; the 'allnodes' list which is a singly linked list containing every node in the tree, and the child->parent structure where each parent node has a singly linked list of children. All of the data in the allnodes list can be easily reproduced with the parent-child lists, so of_allnodes is actually unnecessary. Remove it entirely which saves a bit of memory and simplifies the data structure quite a lot.
