在匹配的过程中会调用probe函数。 在bus.c中会出现static int bus_match(struct device * dev, struct device_driver * drv)，这个函数就会调用 if (drv->probe) { if ((error = drv->probe(dev))) { dev->driver = NULL; return error; }，这个时候就是调用Probe的时候了。

Linux Device的注册最终都是通过device_register()实现,Driver的注册最终都是通过driver_register()实现。下图对照说明了Device和Driver的注册过程。 上面的图解一目了然,详细过程不再赘述。注意以下几点说明: BUS的p->drivers_autoprobe;1默认是true。 bus_for_each_drv()是对BUS上所有的Driver都进行__device_attach...
