Thank you,
I already saw the first tutorial of Borkim Sachar, and gave him some try, but it had yet some imprecision that made it difficult to follow.
In the meantime I have read the russian article where there is the fundament, and better understood Sachim's also.
I then was able to repeat the passages of his tutorial.
Now I see he did a newer more detailed version in the link you gave me, so it's better I also comment there, as it's more recent.
I have not yet solved my problem, because tpd_i2c_probe is not in my kallsyms list.
I'll refer my details in the new thread.
Best regards.
