[PATCH 09/14] Big kfree NULL check cleanup - misc remaining drivers

From: Jesper Juhl
Date: Thu Oct 13 2005 - 14:26:27 EST


This is the remaining misc drivers/ part of the big kfree cleanup patch.

Remove pointless checks for NULL prior to calling kfree() in misc files in drivers/.


Sorry about the long Cc: list, but I wanted to make sure I included everyone
who's code I've changed with this patch.
