From 3941a3aa4b653b69876d894d08f3fff1cc965267 Mon Sep 17 00:00:00 2001 From: Alex Hung Date: Fri, 19 Apr 2024 20:23:36 -0600 Subject: [PATCH] drm/amd/display: Fix incorrect size calculation for loop [WHY] fe_clk_en has size of 5 but sizeof(fe_clk_en) has byte size 20 which is lager than the array size. [HOW] Divide byte size 20 by its element size. This fixes 2 OVERRUN issues reported by Coverity.
