    Hi William,
    
    I love your patch! Perhaps something to improve:
    
    [auto build test WARNING on stm32/stm32-next]
    [cannot apply to linus/master linux/master v5.7-rc3 next-20200430]
    [if your patch is applied to the wrong git tree, please drop us a note to help
    improve the system. BTW, we also suggest to use '--base' option to specify the
    base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
