Subject: [PATCH v3 2/4] MdeModulePkg/HiiDatabaseDxe: ASSERT StringPtr
Date: Fri, 1 Nov 2019 14:14:15 +0800 [thread overview]
Message-ID: <20191101061417.28896-3-shenglei.zhang@intel.com> (raw)
In-Reply-To: <20191101061417.28896-1-shenglei.zhang@intel.com>
The caller of CompareAndMergeDefaultString has checked that
AltCfgResp must contain AltConfigHdr. So we add ASSERT to assume
StringPtr is not NULL.
