deepinlinux v23安装pl2303的usb串口驱动

deepinlinux v23安装pl2303的usb串口驱动，以前v15 v20时代做过，以为很简单，谁知一番折腾下来又涨知识了

先下载linux源码，准备编译，从v23看内核远高于驱动源码，找一个源码最高级开编，先复制以下原编译步骤

1. terminal			// open terminal AP. S1.png
2. uname -r			// found out the nearest Linux kernel version first , S2.png
3. make all			// make new driver, if you have meet error message during make kernel driver, please send email to us. , S3.png
4. sudo cp pl2303.ko /lib/modules/$(uname -r)/kernel/drivers/usb/serial
				// copy new driver to kernel. S4.png
5. sudo gedit /etc/modules	// edit modules ,  S5.png
6. pl2303			// add pl2303, save, close modules   , S6.png
7. reboot			// reboot OS , S7.png
8. plug in new cable, and then enjoy!

卡在第一步，编译不过，系统化默认gcc有些编译不过，几经折腾

查看报错类型，指针强转错误
找到源文件最下面pl2303_device结构体里
