Hi Wolfram, I know you asked for just the core patch, but since I'm not aware of anything else I thought I'd just send both, and hopefully that will be the end of it for this cycle. We'll see... These patches verify the device id of the PCA984x mux chips using standardized (but rarely implemented) i2c device identification.
