From 49a78b05d5ca1e23fd737747a8757b8bdc319b30 Mon Sep 17 00:00:00 2001 From: Yajun Deng Date: Thu, 4 Jan 2024 11:28:22 +0800 Subject: USB: core: Use device_driver directly in struct usb_driver and usb_device_driver 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.
