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,
