Subject: [PATCH] AdvancedFeaturePkg/BmcElog: Change arithmetic logic
Date: Mon,  2 Sep 2019 20:05:13 +0800	[thread overview]
Message-ID: <20190902120514.18028-1-shenglei.zhang@intel.com> (raw)

Change the value from "sizeof(UINT8)" to 1 in the arithmetic expression.
The original value added to (UINT8 *)&GetBmcGlobalEnables is
(sizeof(UINT8)*sizeof(UINT8)) which equals to 1, so the functionality
looks right. But the arithmetic logic is actually wrong.
