/**
 * struct faux_device_ops - a set of callbacks for a struct faux_device
 * @probe:	called when a faux device is probed by the driver core
 *		before the device is fully bound to the internal faux bus
 *		code.  If probe succeeds, return 0, otherwise return a
 *		negative error number to stop the probe sequence from
 *		succeeding.
 * @remove:	called when a faux device is removed from the system
 *
 * Both @probe and @remove are optional, if not needed, set to NULL.
