I'm not sure I read you correctly so, for clarity: the patch introducing I2C_FUNC_NOSTART finally landed in my tree [1], not Wolfram's. It will be merged in kernel 3.5. [1] http://khali.linux-fr.org/devel/linux-3/jdelvare-i2c/ If you don't want to depend on that, then just use I2C_FUNC_PROTOCOL_MANGLING for now and you can switch to I2C_FUNC_NOSTART later. -- Jean Delvare
