Hi,
Please indent Kconfig keywords with one tab only, and indent
help text with one tab + 2 spaces, as documented in
Documentation/process/coding-style.rst:

"""
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.
"""
