Ah, that's in the help text. I guess that those can be ignored simply 
based on the indentation.

I also see these:

drivers/i2c/busses/Kconfig:       to also select CONFIG_TYPEC_FUSB302=m.
drivers/platform/chrome/Kconfig:        select CONFIG_MFD_CROS_EC_DEV

The 2nd looks like it's incorrect.

And then also:
$ git grep 'depends on\b.*\bCONFIG_' -- '*/Kconfig*'
samples/Kconfig:        depends on CONFIG_ANDROID_BINDERFS

Thanks,
John
