From a1bf09e69f8e938fef85f18c117ac390a48f7763 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 18 Jul 2016 16:06:18 +0200 Subject: [PATCH] drm/ttm: Delete an unnecessary check before the function call "ttm_tt_destroy" The ttm_tt_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
