Later, acpi_memory_device_add() calls add_memory() for each ACPI memory device object as it enumerates ACPI namespace. This add_memory() call is expected to fail in register_memory_resource() at boot since iomem_resource has been set up from EFI/e820. As a result, add_memory() returns -EEXIST, which acpi_memory_device_add() handles as the normal case. This scheme works fine, but the following error message is logged for every ACPI memory device object during boot-up. "System RAM resource %pR cannot be added\n" This patch changes register_memory_resource() to use pr_debug() for the message as it shows up under the normal case.
