Besides the *presumed* OpenProtocol(... BY_DRIVER ...) /
EFI_ACCESS_DENIED conflict between the two drivers that we've been
discussing, which IMHO would merit an update to the commit message, I
think the DSC files should be modified similarly:
"OvmfPkg/QemuVideoDxe/QemuVideoDxe.inf {...}" should depend on
!ifndef $(CSM_ENABLE)
; the GOP shouldn't be built at all if we're not including it in the
firmware image.
Thanks
