[PATCH] i2c: remove obsolete cleanup for clientdata

From: Wolfram Sang
Date: Mon Aug 23 2010 - 11:07:03 EST


A few new i2c-drivers came into the kernel which clear the clientdata-pointer
on exit. This is obsolete meanwhile, so fix it and hope the word will spread.

Jean, I dunno if it fits for 2.6.36. It is not precisely a regression.
Though, if it enters with the next merge window, the next set of "faulty"
drivers may come in at the same time...
