[Liu Shixin]

drivers/i2c/busses/i2c-mlxbf.c: In function ‘mlxbf_i2c_acpi_probe’:
drivers/i2c/busses/i2c-mlxbf.c:2296:8: error: implicit declaration of function 
‘acpi_device_uid’; did you mean ‘cpu_device_up’? 
[-Werror=implicit-function-declaration]
  uid = acpi_device_uid(adev);
        ^~~~~~~~~~~~~~~
        cpu_device_up
