[PATCH 16/16] Staging: hv: Remove the vm_device structure
From: K. Y. Srinivasan
Date: Mon Mar 07 2011 - 16:26:37 EST
Consolidate all device related state in struct hv_device by
moving the device field from struct vm_device to
struct hv_device. As part of this, also get rid of struct
vm_device since the consolidation is complete.
