Yes, provided your driver specified list of adapters-address pairs, which should be in any of the "<forces, probe, (normal_i2c + ignore)>" member of struct i2c_client_address_data has "ANY_I2C_BUS" as adapter id. I saw the code, but i didnt get the difference between the three members viz.. forces, probe and ignore. AFAI understood is that any one of these three arrays should have your adapter-address pair, and a bit different in case of "ignore" which checks with normal_i2c[]. anyone??? cheers, sandeep. > > Thank You > naziir > > > > > > Erik > > > > -- > > They're all fools.
