If you need this interface, use the updated i2c-dev.h that > is in the lmsensors release. That is the proper file. I think you create a mess here. Other drivers have usable API include files in /usr/include/linux, why are i2c.h and i2c-dev.h special? While I can understand why the ioctl wrappers have been removed from the kernel include file i2c-dev.h I fail to see the logic in having a different i2c-dev.h for userspace, or generally breaking the kernel includes for userspace. It seems to me that there is no package that I could install to make the correct i2c-dev.h available for userspace programs, and the only way to fix the DirectFB Matrox driver so it compiles with 2.4 and 2.6 kernel headers is to copy the correct i2c-dev.h into the DirectFB source tree. I think that sucks. Johannes
