This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit c6c0a6637f9da54f9472144d44f71cf847f92e20 upstream.
The kfree() function already NULL checks the parameter so remove the
redundant NULL checks before kfree() calls in arch/mips/kvm/.
