build error inside i2c.cpp

[shantanubanerjee]

A great contribution.
I have tried to build this source but I got some error.

make menuconfig

and change the default serial port to /dev/ttyUSB0 but every time I am getting the below error.

line 50 becomes:

    i2c_master_read_byte(cmd, buf, (len == 1) ? I2C_MASTER_NACK : I2C_MASTER_ACK );

line 77 becomes:

i2c_master_read_byte(cmd, &buf, I2C_MASTER_NACK );
