on x86_64:

ld: drivers/mfd/simple-mfd-i2c.o: in function `simple_mfd_i2c_probe':
simple-mfd-i2c.c:(.text+0x48): undefined reference to `__devm_regmap_init_i2c'

CONFIG_I2C=m
CONFIG_MFD_SIMPLE_MFD_I2C=y
CONFIG_MFD_SL28CPLD=y


Is linux-next missing the source code for CONFIG_MFD_SL28CPLD?


The build error is caused by:

config MFD_SL28CPLD
	tristate "Kontron sl28cpld Board Management Controller"
	select MFD_SIMPLE_MFD_I2C

that "select" when "depends on I2C" is absent/missing.
