From 0e88348e4b252cd68b88e1d87085208be2293651 Mon Sep 17 00:00:00 2001 From: Ruiyu Ni Date: Mon, 9 Jan 2017 16:45:40 +0800 Subject: [PATCH] ShellPkg/HandleParsingLib: Return NULL name for unknown GUID GetStringNameFromGuid() returns NULL for unknown GUID, instead of returning "UnknownDevice". The behavior change matches ShellProtocol.GetGuidName().
