Subject: [PATCH 3.10 35/46] MIPS: KVM: Remove redundant NULL checks before kfree()
Date: Fri, 4 Jul 2014 15:19:39 -0700 [thread overview]
Message-ID: <20140704221603.877830670@linuxfoundation.org> (raw)
In-Reply-To: <20140704221602.280733370@linuxfoundation.org>
3.10-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/.
