There is usbdrv_wrap in struct usb_driver and usb_device_driver, it contains device_driver and for_devices. for_devices is used to distinguish between device drivers and interface drivers. Like the is_usb_device(), it tests the type of the device. We can test that if the probe of device_driver is equal to usb_probe_device in is_usb_device_driver(), and then the struct usbdrv_wrap is no longer needed. Clean up struct usbdrv_wrap, use device_driver directly in struct usb_driver and usb_device_driver. This makes the code cleaner.
