From c8aa72633e65c5c215b0cdd9970642e2a4f9a9a3 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 12 Mar 2007 14:41:45 -0600 Subject: [PATCH] [POWERPC] bootwrapper: Make ft_get_phandle() accept and return NULL. Currently, if ft_get_phandle() is passed NULL it will allocate an entry for it and return a non-NULL phandle. This patch makes it simply pass the NULL through.
