From a204ea8c20773a21c7fabbc21dab1cd104fa5a97 Mon Sep 17 00:00:00 2001 From: Tuo Li Date: Tue, 3 Aug 2021 18:51:32 -0700 Subject: [PATCH] drm/amdgpu: drop redundant null-pointer checks in amdgpu_ttm_tt_populate() and amdgpu_ttm_tt_unpopulate() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The varialbe gtt in the function amdgpu_ttm_tt_populate() and amdgpu_ttm_tt_unpopulate() is guaranteed to be not NULL in the context. Thus the null-pointer checks are redundant and can be dropped.
