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.
