From eeef3c18256f1f9a757f0e017c0464832c31f713 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 28 Oct 2020 12:43:16 +0000 Subject: [PATCH] drm/amd/pm: fix out-of-bound read on pptable->SkuReserved A recent change added two uint16_t elements to PPTable_t and reduced the uint32_t array down to 8 elements. This results in the dev_info printing of pptable->SkuReserved[8] accessing a value that is out-of-range on array SkuReserved. The array has been shrunk by 1 element, so remove this extraneous dev_info message.
