- We have to carry this downstream-only patch -- committed originally as

- To avoid confusion, remove the tags from the commit message that had
|
|
|
6009e6 |
been added by the downstream maintainer scripts, such as: Message-id,
|
|
|
6009e6 |
Patchwork-id, O-Subject, Acked-by. These remain available on the
|
|
|
6009e6 |
original downstream commit. The Bugzilla line is preserved, as it
|
|
|
6009e6 |
doesn't relate to a specific posting, but to the problem.

Bugzilla: 1714446
|
|
|
6009e6 |
|
|
|
6009e6 |
To suppress an error message on the silent build when ramfb is
|
|
|
6009e6 |
not configured, change QemuRamfbDxe to return EFI_SUCCESS even
|
|
|
6009e6 |
when it fails.
|
|
|
6009e6 |
Some memory is wasted (driver stays resident without
|
|
|
6009e6 |
any good use), but it is mostly harmless, as the memory
|
|
|
6009e6 |
is released by the OS after ExitBootServices().
