From c171fef5c8566cf5f57877e7832fa696ecdf5228 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 20 Jan 2006 14:08:59 -0800 Subject: [PATCH] kobject_add() must have a valid name in order to succeed. So we might as well check to verify this, and let the user know that something is wrong if they didn't do it correctly, instead of oopsing later on in kobject_get_name() or somewhere else.
