Drivers: hv: vmbus: Don't wait for the ACPI device upon initialization Waiting to 5 seconds in case of missing VMBus ACPI device is redundant as the device is either present already or won't be available at all. This patch enforces synchronous probing to make sure the bus traversal, happening upon driver registering will either find the device (if present) or not spend any additional time if device is absent.
