From dc71bcf1b99c265fffdb1e8c60e7933612f3bca7 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Sat, 19 Jan 2013 10:20:42 -0800 Subject: of: fix incorrect return value of of_find_matching_node_and_match() The of_find_matching_node_and_match() function incorrectly sets the matched entry to 'matches' when the compatible value of a node matches one of the possible values. This results in incorrectly selecting the the first entry in the 'matches' list as the matched entry. Fix this by noting down the result of the call to of_match_node() and setting that as the matched entry.
