Linux Virtualization - Mar 2011 - [PATCH 05/16] Staging: hv: Change the signature for vmbus_child_driver_register

In preparation for moving the element driver from the
struct driver_context to struct hv_driver, change the
signature for the function vmbus_child_driver_register()
to take a pointer to struct device_driver.
