这家伙很懒，什么也没写！

这家伙很懒，什么也没写！

```c
const static struct rt_pin_ops _stm32_pin_ops =
{
    stm32_pin_mode,
    stm32_pin_write,
    stm32_pin_read,
    stm32_pin_attach_irq,
    stm32_pin_dettach_irq,
    stm32_pin_irq_enable,
};
```

提示类型不兼容

```
../drivers/drv_gpio.c:633:5: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
     stm32_pin_mode,
     ^
../drivers/drv_gpio.c:633:5: note: (near initialization for '_stm32_pin_ops.pin_mode')

     stm32_pin_write,
     ^

../drivers/drv_gpio.c:636:5: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
     stm32_pin_attach_irq,
     ^
../drivers/drv_gpio.c:636:5: note: (near initialization for '_stm32_pin_ops.pin_attach_irq')
../drivers/drv_gpio.c:638:5: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
     stm32_pin_irq_enable,
     ^
../drivers/drv_gpio.c:638:5: note: (near initialization for '_stm32_pin_ops.pin_irq_enable')
```

原函数是：

```c
struct rt_pin_ops
{
    void (*pin_mode)(struct rt_device *device, rt_base_t pin, rt_uint8_t mode);
    void (*pin_write)(struct rt_device *device, rt_base_t pin, rt_uint8_t value);
    rt_ssize_t  (*pin_read)(struct rt_device *device, rt_base_t pin);
    rt_err_t (*pin_attach_irq)(struct rt_device *device, rt_base_t pin,
            rt_uint8_t mode, void (*hdr)(void *args), void *args);
    rt_err_t (*pin_detach_irq)(struct rt_device *device, rt_base_t pin);
    rt_err_t (*pin_irq_enable)(struct rt_device *device, rt_base_t pin, rt_uint8_t enabled);
    rt_base_t (*pin_get)(const char *name);
#ifdef RT_USING_DM
    rt_err_t (*pin_irq_mode)(struct rt_device *device, rt_base_t pin, rt_uint8_t mode);
    rt_ssize_t (*pin_parse)(struct rt_device *device, struct rt_ofw_cell_args *args, rt_uint32_t *flags);
#endif
#ifdef RT_USING_PINCTRL
    rt_err_t (*pin_ctrl_confs_apply)(struct rt_device *device, void *fw_conf_np);
#endif /* RT_USING_PINCTRL */
};
```
