From aeffc8fb2174f017a10df114bc312f899904dc68 Mon Sep 17 00:00:00 2001 From: Aurabindo Pillai Date: Fri, 25 Nov 2022 19:13:41 -0500 Subject: [PATCH] drm/amd/display: fix array index out of bound error in DCN32 DML [Why&How] LinkCapacitySupport array is indexed with the number of voltage states and not the number of max DPPs. Fix the error by changing the array declaration to use the correct (larger) array size of total number of voltage states.
