Subject: Remove clientdata before kfree?

Hi Jean,
I am teaching myself coccinelle at the moment and created a semantic patch
which detects missing 'i2c_set_clientdata(client, NULL)' before freeing the
used data-structure. There are a number of drivers missing that.
While doing this, it is also trivial to change a few drivers to FIRST use
i2c_set_clientdata() and THEN kfree (those few are doing it the other way
around). I think it is cleaner this way, but probably doesn't matter much in
reality. So, should I do this transformation or rather drop it (which is also
trivial ;)).
Kind regards,
Wolfram
