I understand what the patch is trying to do, but when we already have
IS_ENABLED() in <linux/kconfig.h> this syntax becomes a big cognitive
confusion for the mind.
At least the commit needs to explain why it doesn't work to use
IS_ENABLED() instead so that this is needed.
Certainly the build failures must be possible to solve so that this
can live with the sibling IS_ENABLED() inside <linux/kconfig.h>,
it can't be too hard.
