    gpio: return -ENOTSUPP if debounce cannot be set · 65d87656
    Linus Walleij 提交于
    It appears some drivers are using gpio_set_debounce()
    opportunistically, i.e. without knowing whether it works or
    not. (Example: input/keyboard/gpio_keys.c) to account for
    this use case, return -ENOTSUPP and do not print any
    warnings in this case.
    
    Took a round over the other gpio_set_debounce() consumers
    to make sure that none of them are relying on the returned
    error code to be something specific.
