From b365b3daf2a9e2a8b002ea9fef877af1c71513fd Mon Sep 17 00:00:00 2001 From: Chuck Ebbert <76306.1226@compuserve.com> Date: Thu, 12 Jan 2006 20:02:00 -0500 Subject: [PATCH] [PATCH] kobject: don't oops on null kobject.name kobject_get_path() will oops if one of the component names is NULL. Fix that by returning NULL instead of oopsing.
