misc: eeprom: Export I2C module alias information in missing drivers 2015-08-10T06:37:36+00:00 Javier Martinez Canillas javier@osg.samsung.com 2015-08-07T12:04:19+00:00 c49c1f0873faddf78c3545a8e25dfe23e8d15c2f The I2C core always reports the MODALIAS uevent as "i2c:<client name>" regardless if the driver later is match using the I2C id_table or the of_match_table. So the driver needs to export the I2C table and this be built into the module or udev won't have the necessary information to auto load the correct module when the device is added.
