[PATCH 04/39] debugobjects: drop null test before destroy functions

From: Julia Lawall
Date: Sun Sep 13 2015 - 08:36:50 EST


Remove unneeded NULL test.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@ expression x; @@
-if (x != NULL)
\(kmem_cache_destroy\|mempool_destroy\|dma_pool_destroy\)(x);
// </smpl>
