Does everything else work? I mean ordinary I2C access like read/write. If everything else is fine, just comment out that iic_smbus_quick() call or just don't use i2c_probe(). It's a hack anyway, because I2C spec has no provision for "probing". I wrote this bit-banging implementation just to get some people off my back :). BTW, I never tested my driver on STB4, maybe ocp_defs are wrong (in this case i2c will not work at all). -- Eugene
