Subject: [PATCH RESEND] sched/cpufreq: Fix kobject memleak
Date:   Tue, 30 Apr 2019 10:17:17 +1000
Message-Id: <20190430001717.26533-1-tobin@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently error return from kobject_init_and_add() is not followed by a
call to kobject_put().  This means there is a memory leak.

Add call to kobject_put() in error path of kobject_init_and_add().
