这里是加载ko文件时报的错，ko来自用的教程源码01、例程源码/02、Linux驱动例程/23_multitouch编译出来的。请问这里该怎么修改。
版本5.4.70-00114-g4f2631b022d8-dirty armv7l

这是我的设备树：

1.   edt-ft5x06@38 {
   
2.                 compatible = "edt,edt-ft5206", "edt,edt-ft5x06";
   
3.                 pinctrl-names = "default";
   
4.                 pinctrl-0 = <&pinctrl_tsc
   
5.                  &pinctrl_tsc_reset>;
   
6. 
   
7.                 reg = <0x38>;
   
8.                 interrupt-parent = <&gpio1>;
   
9.                 interrupts = <9 0>;
   
10.                 reset-gpios = <&gpio5 9 GPIO_ACTIVE_LOW>;
    
11.                 irq-gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
    
12.                 status = "okay";
    
13.         };

在恩智浦相关网站上看到有类似问题，说要重新申请一下io，我看教程源码里面确实这样做了。

1. /* 1,申请中断GPIO */
   
2.         if (gpio_is_valid(dev->irq_pin)) {
   
3.                 ret = devm_gpio_request_one(&client->dev, dev->irq_pin,
   
4.                                         GPIOF_IN, "edt-ft5x06 irq");
   
5.                 if (ret) {
   
6.                         dev_err(&client->dev,
   
7.                                 "Failed to request GPIO %d, error %d\n",
   
8.                                 dev->irq_pin, ret);
   
9.                         return ret;
   
10.                 }
    
11.         }
    
12. 
    
13.         /* 2，申请中断,client->irq就是IO中断， */
    
14.         ret = devm_request_threaded_irq(&client->dev, client->irq, NULL,
    
15.                                         ft5x06_handler, IRQF_TRIGGER_FALLING | IRQF_ONESHOT,
    
16.                                         client->name, &ft5x06);
    
17.         if (ret) {
    
18.                 dev_err(&client->dev, "Unable to request touchscreen IRQ.\n");
    
19.                 return ret;
    
20.         }
