USB驅動編譯錯誤

我目前正在嘗試編譯 Linux USB UART 驅動程序，此處提供： http ://www.exar.com/connectivity/uart-and-bridging-solutions/usb-uarts/xr21v1410

該驅動程序由 2 個標頭檔和 1 個大 C 文件組成。這些是 Makefile 的內容：

obj-m := vizzini.o

KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD       := $(shell pwd)

EXTRA_CFLAGS    := -DDEBUG=0

all:
   $(MAKE) -C $(KERNELDIR) M=$(PWD)

modules_install:
   $(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install

clean:
   rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions vtty

這是我執行 make 時編譯器拋出的錯誤：

執行 Linux 核心 3.4.9-2.fc16.x86_64

我將不勝感激任何幫助解決錯誤。

在最新版本的 linux 核心中，usb_serial_register和usb_serial_deregister函式是靜態的。因此，這些函式僅作為文本存在於核心對象文件中。可以改為使用and usb_serial_register_drivers。usb_serial_deregister_drivers

以下是兩組函式的定義：

int usb_serial_register(struct usb_serial_driver *driver);
void usb_serial_deregister(struct usb_serial_driver *device);
int usb_serial_register_drivers(struct usb_driver *udriver,
                               struct usb_serial_driver * const serial_drivers[]);
void usb_serial_deregister_drivers(struct usb_driver *udriver,
                                  struct usb_serial_driver * const serial_drivers[]);

usb_serial_register_drivers需要一個以 NULL 結尾的指向要註冊的 USB 串列驅動程序的指針數組和一個用於匹配設備/介面的 usb_driver。這兩組函式的詳細資訊可以在這裡閱讀：

http://lxr.free-electrons.com/source/drivers/usb/serial/usb-serial.c?v=3.4#L1379

http://www.cs.fsu.edu/~baker/devices/lxr/http/source/linux/drivers/usb/serial/usb-serial.c#L1337

在驅動程序的原始碼中，如下所示的行：

retval = usb_serial_register(&vizzini_device);

被替換為：

struct usb_serial_driver *serial_drivers[2] = {&vizzini_device,NULL};
retval = usb_serial_register_drivers(&vizzini_driver,serial_drivers);

vizzini_driver 和 vizzini_device 在程式碼的其他地方定義如下：

static struct usb_driver vizzini_driver = {
       .name          = "vizzini",
       .probe         = usb_serial_probe,
       .disconnect    = vizzini_disconnect,
       .id_table      = id_table,
       .no_dynamic_id = 1,
};
static struct usb_serial_driver vizzini_device = {
       .driver = {
               .owner =    THIS_MODULE,
               .name =     "vizzini",
       },
   .usb_driver     = &vizzini_driver,
       .description        = "Vizzini USB serial port",
       .id_table           = id_table,
       .calc_num_ports     = vizzini_calc_num_ports,
       .probe              = vizzini_probe,
       .open               = vizzini_open,
       .close              = vizzini_close,
       .write              = vizzini_write,
       .write_room         = vizzini_write_room,
       .ioctl              = vizzini_ioctl,
       .set_termios        = vizzini_set_termios,
       .break_ctl          = vizzini_break_ctl,
       .tiocmget           = vizzini_tiocmget,
       .tiocmset           = vizzini_tiocmset,
       .attach             = vizzini_attach,
       .disconnect        = vizzini_serial_disconnect,
       .release           = vizzini_serial_release,
       .read_int_callback  = vizzini_int_callback,
};
