Remove CONFIG_ACPI_EC. It was always set the same as CONFIG_ACPI, and it had no menu label, so there was no way to set it to anything other than "y". Per section 6.5.4 of the ACPI 3.0b specification, OSPM must make Embedded Controller operation regions, accessed via the Embedded Controllers described in ECDT, available before executing any control method. The ECDT table is optional, but if it is present, the above text means that the EC it describes is a required part of the ACPI subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.
