From d53a64e9ee58c3567955db6147d34f00c90065ed Mon Sep 17 00:00:00 2001 From: Andrey Vatoropin <a.vatoropin@crpt.ru> Date: Wed, 2 Apr 2025 14:21:39 +0000 Subject: [PATCH] drm/amd/display: Remove the redundant NULL check Static analysis shows that pointer "timing" cannot be NULL because it points to the object "struct dc_crtc_timing". Remove the extra NULL check. It is meaningless and harms the readability of the code. Found by Linux Verification Center (linuxtesting.org) with SVACE.
