I lose one day figuring out why my drivers were segfaulting when registring in i2c system. I finally notice that the size of struct adapter is not the same between the headers chipped by the kernel-header and the one given by i2c-source (I guess that i2c-source is the source package for this version of the drivers).
Which files are you speaking about?
yes that's i2c.h
I have check on my system, the definition of i2c_adapter is the same in /usr/src/kernel-headers-2.4.27-2/linux/i2c.h and in /usr/src/modules/i2c/kernel/i2c.h. The ABI is the same, and a driver build with one or with the other header should work.
The main funtions are the same I agree, but take a close look at the sizeof(struct adapter) and you will see that there _is_ a difference which conduct to a kind of buffer overflow :/
If you want I can c&p the 2 structures.
Regards,
Benoit.
