    please drop this this patch. We reached an agreement that a) setting the
    clientdata-pointer to NULL should be done in the i2c-core [1] and b) how to do
    it. Based on that, I will do the modification of the i2c-core for 2.6.34 (as it
    fixes the dangling pointers) and then create one single patch removing the then
    superflous calls to i2c_set_clientdata for 2.6.35 (as it is a cleanup). If you
    already applied the above patch to your branch, you don't have to revert; we
    will fix it for you in the next round.

    Sorry for the detour!

    Kind regards,
