From a8cacc0a45f7d81e6ff1cfe92d38372c0718df9b Mon Sep 17 00:00:00 2001 From: Josh Cartwright Date: Tue, 11 Feb 2014 10:24:02 -0600 Subject: [PATCH] ARM: mvebu: make use of of_find_matching_node_and_match Instead of the of_find_matching_node()/of_match_node() pair, which requires two iterations through the match table, make use of of_find_matching_node_and_match(), which only iterates through the table once. While we're here, mark the of_system_controller table const.
