[PATCH] hp300: fix driver_register() return handling, remove dio_module_init()
Remove the assumption that driver_register() returns the number of devices bound to the driver. In fact, it returns zero for success or a negative error value. dio_module_init() used the device count to automatically unregister and unload drivers that found no devices. That might have worked at one time, but has been broken for some time because dio_register_driver() returned either a negative error or a positive count (never zero). So it could only unregister on failure, when it's not needed anyway. This functionality could be resurrected in individual drivers by counting devices in their .probe() methods.
