"i2c_register_board_info" undefinied

I have tried to compile a kernel driver as module but return me a warning.

Quote:

WARNING: "i2c_register_board_info" ar1020-i2c.ko undefined!

My kernel is 3.6.11

CONFIG_I2C=y
CONFIG_I2C_BOARDINFO=y
CONFIG_I2C_COMPAT=y
CONFIG_I2C_CHARDEV=y

any advice?

Best regards.

Are you compiling it separately from the rest of the kernel? Is your modules.symvers file installed?

Hello smallpond,

Yes, I am compiling it separately from the rest of the kernel?

Are you using the correct make command?
