* Would you like to integrate anything from the following source code variant?

	if (!err)
		/* Create RIS entries described by firmware */
		err = acpi_disabled
		      ? mpam_dt_parse_resources(msc, plat_data)
		      : acpi_mpam_parse_resources(msc, plat_data);

	if (err) {
		if (msc)
			mpam_msc_drv_remove(pdev);
	} else {
		if (fw_num_msc == mpam_num_msc)
			mpam_discovery_complete();
	}

* How do you think about to increase the application of scope-based resource management
  at further places?


Regards,
Markus
