Subject: [EXTERNAL] [edk2-devel] [PATCH v2 7/7] SecurityPkg/HddPassword: Use BaseLib linked list iteration macros

From: Michael Kubacki <michael.kubacki@microsoft.com>

REF:https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.tianocore.org%2Fshow_bug.cgi%3Fid%3D1959&amp;data=02%7C01%7CBret.Barkelew%40microsoft.com%7C0cb7a3e5e3ef4f9c776808d7dd8a2c7e%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637221457829007406&amp;sdata=TzvNo4r7FXEx%2BLEifMTR8HHL%2BGGpl8WkOiABJS1IqF8%3D&amp;reserved=0

Replaces usage of the linked list iteration macros defined in
