It seems that this problem exists since the introduction.

commit 83e2ec765be03e8a8a07619e65df70b48a1db023
Author: George Zhang <georgezhang@vmware.com>
Date: Tue Jan 8 15:53:51 2013 -0800

VMCI: doorbell implementation.

commit 1f166439917b69d3046e2e49fe923579d9181212
Author: George Zhang <georgezhang@vmware.com>
Date: Tue Jan 8 15:55:32 2013 -0800

VMCI: guest side driver implementation.

But this patch should be safe to backport to as old as possible, for
this patch is merely explicitly initializing variables.
