Hi "Ramuthevar,Vadivel, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on balbi-usb/testing/next] [also build test WARNING on usb/usb-testing linus/master v5.7 next-20200608] [cannot apply to linux/master] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system.
