    on i386, when CONFIG_IOSF_MBI=m and
    CONFIG_I2C_DESIGNWARE_BAYTRAIL=y:

    drivers/built-in.o: In function `i2c_dw_eval_lock_support':
    (.text+0x37dd74): undefined reference to `iosf_mbi_available'
    drivers/built-in.o: In function `reset_semaphore.isra.1':
    i2c-designware-baytrail.c:(.text+0x37ddd1): undefined reference to `iosf_mbi_read'
    i2c-designware-baytrail.c:(.text+0x37de13): undefined reference to `iosf_mbi_write'
    drivers/built-in.o: In function `baytrail_i2c_acquire':
    (.text+0x37df26): undefined reference to `iosf_mbi_write'
    drivers/built-in.o: In function `baytrail_i2c_acquire':
    (.text+0x37dfab): undefined reference to `iosf_mbi_read'
    drivers/built-in.o: In function `baytrail_i2c_acquire':
    (.text+0x37e080): undefined reference to `iosf_mbi_read'


    because IOSF_MBI is tristate and I2C_DESIGNWARE_BAYTRAIL is bool:

    config I2C_DESIGNWARE_BAYTRAIL
    bool "Intel Baytrail I2C semaphore support"
    depends on I2C_DESIGNWARE_PLATFORM && IOSF_MBI && ACPI


    I suppose someone could make that:

    depends on I2C_DESIGNWARE_PLATFORM && IOSF_MBI=y && ACPI

    or even make I2C_DESIGNWARE_BAYTRAIL be a tristate symbol.
