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.
Oof. That's embarrassing. Sorry, I'll fix this for v8.
While I'm at it, is the help text required for choice configs?
checkpatch --strict complains with a warning without them, but
I see other places in the tree where help text is omitted for
these configs attached to a choice.
Documentation/process/* doesn't seem to have any guidance, nor
Documentation/kbuild/* on whether it is safe to ignore that
checkpatch warning.
