[PATCH v2] ALSA: aoa: Remove obsolete cleanup for clientdata

From: Axel Lin
Date: Fri Sep 09 2011 - 07:05:01 EST


The i2c core will clear the clientdata pointer automatically.
We don't have to set the `data' field to NULL in remove() or
if probe() failed anymore.

Also remove a unneeded NULL checking for kfree.
