LDD3 linux裝置驅動程式學習之lddbus__linux

1. struct device不再包含bus_id,取而代之的是.init_name，修改ldd_bus

  struct device ldd_bus = {        .init_name = "ldd0",        .release = ldd_bus_release};

修改函數register_ldd_device如下：
   將strncpy(ldddev->dev.bus_id, ldddev->name, BUS_ID_SIZE);
替換為：
   ldddev->dev.init_name = ldddev->name;


修改函數ldd_match如下：
   return !(strncmp(dev->bus_id, driver->name, strlen(driver->name));
修改為
   return !strncmp(dev->init_name, driver->name, strlen(driver->name));

2. 結構體struct bus_type已經改變，不再包含hotplug，取而代之的是uevent，故修改
結構體ldd_bus_type如下：

struct bus_type ldd_bus_type = {        .name = "ldd",        .match = ldd_match,        .uevent = ldd_uevent,};

而原來的函數ldd_hotplug用ldd_event來取代如下：

static int ldd_uevent(struct device *dev, struct kobj_uevent_env *env) {    env->envp[0] = evn->buf;    if (snprintf(env->buf, env->buflen, "LDDBUS_VERSION=%s", Version) >= env->buflen)       return -ENOMEM;   env->envp[1] = NULL;   return 0;}
