Wolfram Sang fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
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
e4a7b9b04d 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.

README

Todo:
	- checkpatch.pl cleanups
	- sparse cleanups
	- lots of little modules, should be merged together
	  and added to the build.
	- testing?
	- handle churn in v4l layer.

Please send patchs to Greg Kroah-Hartman <greg@kroah.com> and Cc: Ross
Cohen <rcohen@snurgle.org> as well.
