Subject: [patch] nouveau: fix memory leak
Date: Wed, 07 Apr 2010 09:33:36 +0000	[thread overview]
Message-ID: <20100407093336.GE5157@bicker> (raw)

In the original code there was a typo and we called kfree(pgraph->ctxprog)
two times instead of kfree(pgraph->ctxvals);

Also it's OK to pass NULL variables to kfree().  checkpatch.pl complains 
about this so I removed the checks.
