From 75c28c09af99a0db0ccd8b4395469761aa736543 Mon Sep 17 00:00:00 2001 From: Leif Lindholm Date: Fri, 28 Nov 2014 11:34:28 +0000 Subject: of: add optional options parameter to of_find_node_by_path() Update of_find_node_by_path(): 1) Rename function to of_find_node_opts_by_path(), adding an optional pointer argument. Provide a static inline wrapper version of of_find_node_by_path() which calls the new function with NULL as the optional argument. 2) Ignore any part of the path beyond and including the ':' separator. 3) Set the new provided pointer argument to the beginning of the string following the ':' separator. 4: Add tests.
