    semi-bot:

    Please follow coding-style for Kconfig files:

    (from Documentation/process/coding-style.rst, section 10):

    For all of the Kconfig* configuration files throughout the source tree,
    the indentation is somewhat different. Lines under a ``config`` definition
    are indented with one tab, while help text is indented an additional two
    spaces.


    thanks.
