How about actually adding some meaningful help texts instead
(as a general rule each user visible option should have valid
help text)?

Please add a missing help text instead (take a look at FB_SAVAGE_I2C
config option to see how a valid help text entry should look like).

In the longer term we should consider removing *_I2C config options
and just make the main config options always enable I2C subsystem
directly if needed/useful (some fbdev drivers are doing it this way
already).
