If you use i2c_new_device() then it's alright.
Right. Conceptually the way that the i2c core uses "numbered" adapters and registered board_info could be viewed as a way to let platforms avoid tracking that stuff themselves. Since the of_* framework is already tracking that, there's no big win in trying to have i2c-core track that too, on its behalf. - Dave _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
