Date: Mon, 16 Nov 2015 08:28:55 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: linux-kernel@...r.kernel.org, linux-sh@...r.kernel.org Cc: kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] sh-DWARF: Delete unnecessary checks before the function call "mempool_destroy" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Mon, 16 Nov 2015 08:20:36 +0100 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.
