Subject: [PATCH 2/4][Trivial] lib/kobject.c : Check parameter in kobject_set_name
Date: Sat, 21 Apr 2012 17:31:24 +0800 [thread overview]
Message-ID: <1335000692.2188.10.camel@yan> (raw)
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.
