Subject: [EXTERNAL] [edk2-devel] [PATCH v2 6/7] MdeModulePkg/RamDiskDxe: 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%7C12b6ab8be60a43c8326808d7dd8a2a52%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637221457789115342&amp;sdata=SoQ2JMwtD84nofSN%2B0Ge71u1hTL%2BFds8FcmWYcPd39o%3D&amp;reserved=0

Replaces usage of the linked list iteration macros defined in RamDiskImpl.h
with the common definition in BaseLib.h.
