Subject: [PATCH 3.14 49/59] MIPS: KVM: Remove redundant NULL checks before kfree()
Date: Fri,  4 Jul 2014 15:19:38 -0700	[thread overview]
Message-ID: <20140704221541.880963895@linuxfoundation.org> (raw)
In-Reply-To: <20140704221539.544876024@linuxfoundation.org>

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: James Hogan <james.hogan@imgtec.com>

commit c6c0a6637f9da54f9472144d44f71cf847f92e20 upstream.

The kfree() function already NULL checks the parameter so remove the
redundant NULL checks before kfree() calls in arch/mips/kvm/.
