The patch fixed the code depending on the exact order of fields in the struct vmbus_driver_context, so the unused field drv_ctx can be removed, and drv_obj doesn't have to be the second field in this structure.

Hyper-V has maintained both its class independent driver and device state in two independent data structures: Driver state: struct driver_context (vmbus.h) and struct hv_driver (vmbus_api.h) Device state: struct vm_device (vmbus.h) and struct hv_device (vmbus_api.h) While sruct driver_context and struct vm_device embed generic Linux abstractions of struct device_driver and struct device
