So thinking some more about this, I can put the device_property check
inside the fw_get_efi_embedded_fw() call, as well as modify opt_flags
there to or in FW_OPT_NOCACHE on success, then together with the discussed
changed to drop the #ifdef, the code would look like this:

         ret = fw_get_filesystem_firmware(device, fw->priv);
	if (ret)
		fw_get_efi_embedded_fw(device, fw->priv, &opt_flags, ret);
	if (ret)
                 if (!(opt_flags & FW_OPT_NO_WARN))
                         dev_warn(device,
	...

With just these 2 lines being new:

	if (ret)
		fw_get_efi_embedded_fw(device, fw->priv, &opt_flags, ret);

So the main.c changes will be nice and clean then.
