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/.
