All errors (new ones prefixed by >>):
drivers/i2c/i2c-core-base.o: In function `i2c_register_adapter':
drivers/i2c/i2c-core-base.c:1262: undefined reference to `of_i2c_setup_smbus_alert'
I understand how this is occurring.
I2C=y, OF=y and I2C_PARPORT=m
I2C_PARPORT selects I2C_SMBUS setting it to m
Calling a function in i2c-smbus (module) from i2c-core (builtin) is then a problem.
However there doesn't seem to be a way (that I can see) to have select statement force I2C_SMBUS=y if I2C=y
Can I get a hint on what the correct course of action is.
