Subject[PATCH 1/1] Stage: hv: Rename struct device_context and re-arrange the fields inside (re-formatted)
Date
From: Haiyang Zhang <haiyangz@microsoft.com>

Rename struct device_context and re-arrange the fields inside.
Rename struct device_context to struct vm_device, and move
struct device field to the end according to Document/driver-model standard.
