From: Christian Borntraeger <borntraeger@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit f2a25160887e00434ce1361007009120e1fecbda upstream.
__kvm_set_memory_region sets r to EINVAL very early.
Doing it again is not necessary. The same is true later on, where
r is assigned -ENOMEM twice.
