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.
