From 206b7b9aba46768ef946e50d0e297a4a21b44e88 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Thu, 29 May 2014 10:16:44 +0100 Subject: [PATCH] MIPS: KVM: Remove redundant NULL checks before kfree() commit c6c0a6637f9da54f9472144d44f71cf847f92e20 upstream. The kfree() function already NULL checks the parameter so remove the redundant NULL checks before kfree() calls in arch/mips/kvm/.
