That would be part of a detect-callback. In probe() the device is already considered to be present. But you can instantiate devices at runtime if you want to add the eeprom dynamically (Documentation/i2c/instantiating-devices) Regards, Wolfram -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
