2. 部分代码

代码如下：

static int mmc_bus_probe(struct device *dev)
{
    struct mmc_driver *drv = to_mmc_driver(dev->driver);
    struct mmc_card *card = mmc_dev_to_card(dev);

    return drv->probe(card);
}

static int mmc_bus_remove(struct device *dev)
{
    struct mmc_driver *drv = to_mmc_driver(dev->driver);
    struct mmc_card *card = mmc_dev_to_card(dev);

    drv->remove(card);

    return 0;
}
