Subject[PATCH 23/48] KVM: Clean up coalesced_mmio destruction
Date
From: Gregory Haskins <ghaskins@novell.com>

We invoke kfree() on a data member instead of the structure. This works today
because the kvm_io_device is the first element of the private structure, but
this could change in the future, so lets clean this up.
