-Subject: [PATCH] of: Make of_find_node_by_path() handle /aliases
-
-Make of_find_node_by_path() handle aliases as prefixes. To make this
-work the name search is refactored to search by path component instead
-of by full string. This should be a more efficient search, and it makes
-it possible to start a search at a subnode of a tree.
