Subject: Re: [Patch 2/3] SecurityPkg/TcgStorageOpalLib: Add supports for pyrite 2.0 spec.
Date: Mon, 7 May 2018 03:08:30 +0000	[thread overview]
Message-ID: <B80AF82E9BFB8E4FBD8C89DA810C6A0931D99A56@SHSMSX104.ccr.corp.intel.com> (raw)
In-Reply-To: <20180503031702.11296-3-eric.dong@intel.com>

Some minor comments:
1. In file TcgStorageOpalCore.c, the function description comment for
OpalGetFeatureDescriptor() seems not matching the function itself. Please help
to update.

2. For file TcgStorageOpalUtil.c, the copyright year format seems not proper.
Also, maybe double quotes can be used instead of brackets for:
#include <TcgStorageOpalLibInternal.h>

Other than the above comments, the patch is good to me.
Reviewed-by: Hao Wu <hao.a.wu@intel.com>

Best Regards,
Hao Wu
