在T113S3平台上移植开机动画播放，参考大佬的移植教程，但在移植的过程中遇到了内核崩溃的问题，如下：

加打印跟踪代码到内核的/kernel/linux-5.4/drivers/media/cedar-ve/cedar_ve.c 文件下的cedar_get_device（void）函数里面
struct device *cedar_get_device(void)
{
    if (!cedar_devp) {
        pr_err("cedar_devp is NULL\n");
        // return NULL;
    }
    printk("cedar_devp: %p, plat_dev: %p\n", cedar_devp, cedar_devp->plat_dev);
    return cedar_devp->plat_dev;
}
EXPORT_SYMBOL(cedar_get_device);

加打印发现，只要读取结构体的地址，内核就会因为内存的问题崩溃，有无大佬遇到同样情况，请求指点一二，感激不尽。
