+Subject: [PATCH] OvmfPkg: QemuRamfbDxe: Do not report DXE failure on Aarch64
+ silent builds (RH only)

+- We have to carry this downstream-only patch -- committed originally as
+  aaaedc1e2cfd -- indefinitely.
+
+- To avoid confusion, remove the tags from the commit message that had
+  been added by the downstream maintainer scripts, such as: Message-id,
+  Patchwork-id, O-Subject, Acked-by. These remain available on the
+  original downstream commit. The Bugzilla line is preserved, as it
+  doesn't relate to a specific posting, but to the problem.
+
+Bugzilla: 1714446
+
+To suppress an error message on the silent build when ramfb is
+not configured, change QemuRamfbDxe to return EFI_SUCCESS even
+when it fails.
+Some memory is wasted (driver stays resident without
+any good use), but it is mostly harmless, as the memory
+is released by the OS after ExitBootServices().
