Hi, I love your patch! Perhaps something to improve: [auto build test WARNING on usb/usb-testing] [also build test WARNING on balbi-usb/next peter.chen-usb/ci-for-usb-next linus/master linux/master v5.6-rc7 next-20200327] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system.
