From a63caf13a8037a0e04b9ecabfbcf8e340f33ce8d Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 16 Jul 2016 07:23:42 +0200 Subject: [PATCH] drm/tegra: Delete an unnecessary check before the function call "vunmap" The vunmap() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
