efifb: Implement vga_default_device() (v2)
EFI doesn't typically make use of the legacy VGA ROM, but it may still be configured to pass that through to a given video device. This may lead to an inaccurate choice of default video device. Add support to efifb to pick out the correct active video device. v2: fix if->ifdef Signed-off-by: Matthew Garrett <mjg@redhat.com> Acked-by: hpa@zytor.com Cc: matt.fleming@intel.com Signed-off-by: Dave Airlie <airlied@redhat.com>
