Subject: drm/amd/display: fix array index out of bound error in DCN32 DML
From: Aurabindo Pillai <aurabindo.pillai@xxxxxxx>
commit aeffc8fb2174f017a10df114bc312f899904dc68 upstream.
[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.
