This patch suppresses I2C device probing by clearing the class field
of the "struct i2c_adapter" for the MPC I2C bus adapters. Some board
configurations which rely on probing must be fixed up by adding a
proper I2C device node to the DTS file, like the TQM85xx modules.

Unless you intend to push this patch upstream yourself (through the ppc
tree), you should send it to Ben Dooks (who is in charge of this part
of the i2c subsystem) with Cc to the i2c list.
I just want to mention, that other I2 bus drivers set I2C_CLASS_HWMON as well.
Here are the PowerPC related ones:
$ grep I2C_CLASS_HWMON *
i2c-cpm.c: .class = I2C_CLASS_HWMON | I2C_CLASS_SPD,
i2c-mpc.c: .class = I2C_CLASS_HWMON | I2C_CLASS_SPD,
i2c-ibm_iic.c: adap->class = I2C_CLASS_HWMON | I2C_CLASS_SPD;
i2c-pasemi.c: smbus->adapter.class = I2C_CLASS_HWMON | I2C_CLASS_SPD;
i2c-mv64xxx.c: drv_data->adapter.class = I2C_CLASS_HWMON | I2C_CLASS_SPD;
It would be consequent to remove them as well.
Wolfgang.
