From ecaa8b0ff326920c8a89d748382e1c1d8812676c Mon Sep 17 00:00:00 2001 From: Dave C Boutcher Date: Thu, 12 Jan 2006 16:09:29 -0600 Subject: [PATCH] [PATCH] powerpc: Add of_find_property function Add an of_find_property function that returns a struct property given a property name. Then change the get_property function to use that routine internally.
