Yes, I saw it. You were talking of something like this, right?

/**
 * i2c_slave_mode_detect - detect operation mode
 * @dev:  The device owning the bus
 *
 * This checks the device nodes for a I2C slave by checking the address
 * used.
 *
 * Returns true if a I2C slave is detected, otherwise returns false.
