Hi Wolfram,

I2C-drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

Some more notes:

I waited for rc1 as I knew there were some drivers/patches coming along which
needed to be processed, too.

I'd suggest that this goes via the i2c-tree, so we get rid of all occurences at
once.

Frankly I'd prefer taking input stuff through my tree with the goal of
.36 merge window just to minimize potential merge issues. This is a
simple cleanup patch that has no dependencies, so there is little gain
from doing it all in one go.

Thanks.
