From a316399635e334c878a88c90044c1e45f57129a4 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 16 Nov 2015 08:20:36 +0100 Subject: [PATCH] sh: Delete unnecessary checks before the function call "mempool_destroy" The mempool_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software.
