From c156b584ee820a703073ceda3eaf6cec6afc9966 Mon Sep 17 00:00:00 2001 From: Joe Moore Date: Mon, 25 Nov 2019 05:49:30 -0700 Subject: vc/amd/agesa: Fix uninitialized scalar variable AllocParams.Persist is used uninitialized when calling HeapAllocateBuffer. This could lead to unpredictable or unintended results. The f15tn and f16 versions of AmdS3Save.c have already addressed this by initializing AllocParams.Persist=0 in the same location in the code, so adding to f14 only.
