Date: Sat, 21 Apr 2012 17:31:24 +0800 From: yan <clouds.yan@...il.com> To: greg <gregkh@...uxfoundation.org> Cc: kernel <linux-kernel@...r.kernel.org>, message <message.get@...il.com> Subject: [PATCH 2/4][Trivial] lib/kobject.c : Check parameter in kobject_set_name kobject_set_name is exported and is just a wrapper for kobject_set_name_vargs which does not check its parameter kobj. So check this parameter in kobject_set_name.
