> I picked up most from the kernel patch > (http://www.ensicaen.ismra.fr/~delvare/devel/i2c/linux-2.4.21-i2c-2.8 > .0.patch), in which you also leave out algo_control in your patch for > i2c-algo-bit.c; (Just took a deeper look at the code.) That's because it was unused for that particular algorithm. But it is still used for two other algorithms: ibm_ocp and iop3xx (not build by default). So if i2c-algo-usb was using it, I think we have to leave it there. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
