Note, it says: don't edit.

You set CONFIG_I2C_I801=3Dm while PCI and I2C are both disabled. You
asked for a built breakage, you got it.

You might argue that "make oldconfig" should fix the configuration file
in such a way that the dependencies are correct again. But then this is
a kconfig issue, to be reported to the kconfig maintainer, not me.
