From 7dbe5849fb50fc9b5b77a8f590c87a577ddc9bb6 Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Wed, 27 Aug 2014 17:09:39 +0300 Subject: of: make sure of_alias is initialized before accessing it Simply swap of_alias and of_chosen initialization so that of_alias ends up read first. This must be done because it is accessed couple of lines below when trying to initialize the of_stdout using the alias based legacy method.
