    Subject[PATCH 1/1] Drivers:hv: Fix a bug in vmbus_driver_unregister()
    Date
    The function vmbus_exists() was introduced recently to deal with cases where
    the vmbus driver failed to initialize and yet other Hyper-V drivers attempted
    to register with the vmbus bus driver. This patch introduced a bug where
    vmbus_driver_unregister() would fail to unregister the driver. This patch
    fixes the problem.
