[PATCH 1/4] mfd: Remove obsolete cleanup for clientdata

[Wolfram Sang]

A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit or error. This is obsolete meanwhile, the core will do it.

Nak.

In a module where I plan to do more cleanup and add reference counting
to struct IR, IR_tx, and IR_rx objects, I'd like the explicit "NULL"s in
pointer checks to stay in for now.

Removing the explicit constant "NULL" makes searching for checks against
NULL pointers more difficult when auditing the code (No red syntax
highlighting and a /NULL search misses).

Andy

I agree that Wolfram was too generous with his clean-ups this time.
Wolfram, you should only be removing the calls to i2c_set_clientdata(x,
NULL), not changing the logic of the code.

Furthermore, lirc_zilog is currently undergoing heavy changes, I'd
rather let Andy and Jarod work on that staging driver, and clean up
what needs to be later.

Okay, I will ignore this driver until it comes out of staging.
